Description

The invention relates to a molded ceramic article and a method for manufacturing the same, and particularly to a method for molding a ceramic article. The method can be performed by adding a liquid additive to a powdery mixture as a raw material, and compressing the resulting mixture in a hydrostatic state. The preform, and then the preform certificate is calcined and the molded / healed ceramic article obtained by this method can effectively provide a molded ceramic article with significantly improved v-grindability and corrosion resistance. Previously, β technique hoped to produce molded objects such as ceramics. To obtain its preformed skeleton, there is a uniaxial compression molding method in which the powder mixture as a raw material is compressed in a uniaxial direction; the hydrostatic compression molding method in which the powder mixture is Granulation, compression. Additives for molding are added to the obtained granules and the resulting mixture is compressed under the static pressure of the liquid skull; and a method using an injection molding machine. In the uniaxial compression molding method, ′ is molded by plastically deforming a mixed raw material composed of particles having a plurality of shapes in only one direction to plastically deform it. In this case, the uniaxial compression molding of the powdery mixture alone cannot uniformly apply pressure to the gold and bulk materials. This is due to the differences in friction resistance between adjacent particles and the size and hardness of the particles. It is therefore difficult to obtain a molded article having a uniform density. According to the hydrostatic and compression molding method, equal pressure can be simultaneously applied to the surface of the mixed raw material particles. Therefore, comparing uniaxial compression-molded pellets, a molded article having a more uniform thickness can be obtained. However, this method is the same as the method before the implementation of liquid static compression molding. Generally, the granulation process is required to make the particle size of the mixed raw materials uniform and the liquid additive is added to the particle process to apply 496905 to the particles.

In addition, a dewaxing process is needed in order to remove additives from the resulting preform after molding. In addition, the equipment used in the hydrostatic compression molding method is extremely expensive. From these results, it can be seen that the productivity of the hydrostatic compression molding method is deteriorated, and thus the molded parts obtained by this molding method are relatively expensive. In addition, the injection molding method has been used, and it is particularly desirable to improve the molding time during production, the surface roughness of the preform, and a large amount of productivity. This conventional technique outline includes the following steps. In other words, first of all, the most important is a mixed, finely divided raw material having a desired composition. To improve the fluidity, pressure transmission and moldability of the powdery mixture, add a low viscosity additive composed of organic compounds such as petroleum paraffin and phenol resin to the total weight of 2G-5Gwt. '%, And mix it uniformly Thereby, a mixed raw material is obtained. _In the injection molding method, the mixed raw materials are heated to 120-1281C to improve # fluidity. The mixed raw material after heating is injected into a molding die heated in advance to the same temperature as the mixed raw material for molding, and then cooled and solidified, thereby obtaining a preform. The preform thus obtained is subjected to a so-called dewaxing process (removing the low viscosity additive from the preform), and the preform is calcined to obtain a molded ceramic part. In order to densely mix low viscosity additives and particulate raw materials added at a ratio of up to 2Q-5 0wt.% Of the total weight and feed the mixed raw materials thus obtained into the mold, the fluidity of the mixed raw materials must be improved. To achieve this, * the mold needs to be heated in advance, and in addition, hot particulate materials and low viscosity additives are required. In addition, it is necessary to control the mold temperature in order to obtain a preform by injecting the mixed raw materials into the mold for molding, and then cooling and solidifying. In addition, due to low viscosity additives, organic compounds such as petrolatum A 4 (210X297 mm) (please read the precautions on the back before filling this page)

Composition of the invention () and phenol resin, so there may be disadvantages that will cause the resulting molded parts to become brittle and defective, unless the additives are in advance Decomposed and removed by dewaxing before the molded body is sintered. However, in order to overcome these disadvantages, it is necessary to heat the preform under pressure or reduced pressure for 5-1G days in order to remove the low viscosity additive, in other words, an organic compound without causing a bad effect on the preform. Therefore, the production efficiency is not good 〇 In recent years, a variety of materials have been widely used for molding ceramic parts. For example, ceramic materials and highly durable composite materials are used in various fields. As for its suitable examples, it is worth mentioning the electrode tips of resistance welding machines, circuit breaker contacts that apply large current at any time, and so on. In view of this, Japanese Patent Publication No. 152232/1 989 uses a ceramic-copper composite as the electrode tip. This technical idea is that ceramics such as alumina (Al203) are welded to a copper alloy using a laser beam. The electrode tip edge is formed, and a ceramic film is formed on the electrode tip edge. In addition, as shown in Japanese Patent Laid-Open No. 78683/1799, there is another technical idea in which ceramics are embedded at the distal end of an electrode tip made of a copper alloy, thereby improving durability. In addition, Japanese Patent Laid-Open No. 2 4 7/1 985 shows another technical idea in which a ceramic is mixed with a copper alloy and the resulting mixture is sintered, thereby improving durability. However, the composites shown in the prior art, such as Japanese Patent Publication No. 15 2 2 3/1 9 8 9 ft, have the disadvantage of poor wettability between the copper alloy and the ceramic, so the ceramic is easily separated from the copper alloy. • In addition, the previous A 4 (210X297 mm) shown in Japanese Patent Publication No. 78683/197 (Please read the precautions on the back before filling out this page) • Installation · • Line · 496905 A6 _B_6__ 5. Description of the invention ( ) Technology composites are prone to discharge between copper alloys and ceramics. In addition, when used as an electrode tip of a resistance welding machine, durability is not reliable. On the other hand, taking the prior art shown in Japanese Patent Laid-Open No. 2479/1985 as an example, the durability is only improved by about 20% to 30% compared with the ceramic-free copper alloy / ½¾. Therefore, a durable electrode tip has not been provided so far. In other words, in the ceramic composites shown in the prior art, the copper particles used as the main material of the electrode tip) often have a dendritic structure. It is therefore difficult for particles with different compositions to enter the space within the dendritic structure. Even when the copper particles are spherical, it is only possible to disperse ceramic particles having a particle size in the micrometer range by the conventional method of adding ceramic particles. Therefore, it is impossible to increase the amount of ceramics added without increasing the resistance of the composite. In addition, as the material of the ceramic tip, Cr-Cii alloy can be used in some cases. In order to improve the strength of the maple and prevent the particle species in the weld metal from diffusing into the electrode. However, Cr-Cu alloy has high wettability to the galvanized weld metal. Therefore, when Cir-Cii is used as the electrode material to weld the weld metal, the alloy is welded to the weld metal. In other words, the following disadvantages appear. When metals such as Zn and Fe are incorporated into the Cr.-Cu alloy by welding, Zn, Fe, and Ci: are oxidized by oxygen * in the atmosphere, and the oxide is enlarged to make the alloy structure brittle, and the alloy is cracked and finally 'welded. In addition, the electrical conductivity decreases due to the increase in resistance due to metal penetration. Printed by the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page). In addition, for example, the electrode tips generated by such ceramic molded parts have the following disadvantages depending on the composition of the molded parts. One such disadvantage is illustrated in Figures la and lb. 4 (210X297 mm) 4496905 Printed by the Central Bureau of Standards of the Ministry of Economic Affairs A 6 ___B6_ V. Description of the invention () Figure la shows the electrode tip 10 generated by the Cr-Cii alloy ceramic molded part of the prior art and welding after use . As can be seen in the figure. At the far end, cracks A clearly appear. Figure lb shows the enlarged view of crack A through a 100.x magnification metallurgical microscope. It can be seen that Fel4, Fe, and Zn penetrate the diffusion layer 16 in the structure of the bulk metal 12. To overcome the disadvantages of the former, the following has recently been used as the electrode material: by diffusing the ceramic component composed of alumina into the copper crystal as the bulk metal Alumina dispersed and reinforced copper alloy in structure and sintered. In other words, the space within the copper crystal structure is filled with alumina to prevent the penetration of metals such as Zri and Fe by so-called pinning. When copper is thrown on the electrode tip molded by this method as the bulk metal of the electrode material, copper powder with a dendritic structure is often used. Other metal components are difficult to disperse and penetrate into the space between copper particles with a dendritic structure. On the other hand, when aluminum halide is also dispersed in the space between the particles, it can only disperse particles with a particle size of a few microns. Therefore, the amount of aluminum chloride added as a ceramic component cannot be increased further without increasing the resistance of the copper alloy. In addition, even in the case where an alloy oxidation method is used, oxygen diffusion into the crystal structure, which is necessary for the production of ceramics, is often insufficient. Therefore, the number of ceramics cannot be increased without increasing the resistance of the composite. In other words, even when an alumina-dispersed and reinforced copper alloy is used as an electrode material, a ceramic component composed of fine alumina cannot be dispersed and deposited in a sufficient amount to perform a so-called pinning effect in a space between copper particles. The result is difficult to say when the galvanized welding metal is fused. For example, because of Zri and Fe fM (210X297 mm) (please read the precautions on the back before filling in this page) • Installation · • Wire · 496905 A 6 _B6_ 5. Description of the invention () Welding caused by metal penetration has been resolved. In addition, its service life is only about 20-30% longer than the case of using Cr-Cu alloy as the electrode material. In other words, it is difficult to say that the copper alloy which disperses and strengthens the oxidized oxide is better as an electrode material in terms of its efficacy, due to its complicated production process and high production cost. In addition, even when the intergranular space of the copper powder is filled with sulfonic particles, it cannot be used in large quantities, which is attributed to the decrease in the conductivity of the copper powder. In addition, since the master element is deposited in this way and converted to ceramics without sintering, the dispersion and deposition of dense ceramics are suppressed to prevent the penetration of the metal Zn and Fe. For example, Fig. 2a shows the electrode tip 20 of alumina dispersed in a copper alloy after welding. Yu observed that the so-called pinning-induced cracking B was not achieved uniformly. Figure 2b is an enlarged view of the crack B observed by a metallurgical microscope at a magnification of 100 times. It can be seen that the oxide alloy 26 composed of Fe24 and Fe, Zn, and Cu penetrates, and the diffusion layer 28 composed of outer Zri and Fe diffuses into the interior of the electric tip.

Description of the Invention () Central Standard M of the Ministry of Economic Affairs Figure 31 is an enlarged view of the bridges generated in the transition method according to the preferred embodiment of the manufacturing method of the present invention in Experimental Example I. Detailed description of the fixture example The method of producing a ceramic molded article according to the first embodiment of the present invention by using a uniaxial compression molding machine shown in Fig. 3 will be described later. The uniaxial pressing-shrinking machine ^ includes a lower head 34 and an upper punch 36 / oppositely to each other in the cavity 32 defined in the die 30. In the first step, the raw materials 37 are thoroughly mixed to form a mixture, which is composed of a powder having a high modulus of elasticity and a powder having a low modulus of elasticity, such as a metal-ceramic composite, a powder composed of fine dendritic crystals such as electrolyte powder , Is a plate crystal made of quenched and condensed powder, or a powder with sharp corners, and a liquid additive 39 is added to the mixture as a liquid phase product. The liquid additive 39 in this example may be selected from water, alcohols such as ethanol, methanol and isopropanol, aromatic compounds such as toluene, xylene benzene and saturated organic compounds such as hexane. Therefore, it is necessary to add the additive 39 in an amount suitable for filling the space of the raw material 37 to obtain the hydrostatic pressure, as described later. The amount must be set in advance according to the shape, type, particle size, particle size distribution, etc. of the powder used. It is particularly suitable to add the liquid additive .39 at a ratio of 10-30 wt.% (Mainly 100 wt ·% raw material 37). In the second step, the first mixture 38 is pseudo-composed of the raw material 37 and the liquid additive 39 inside the cavity 32 of the uniaxial compression molding machine shown in FIG. 3. The mixture 38 is then performed using the lower punch 34 and the upper punch 36 (please read the precautions on the back before filling out this page). • Assembly · • Wire · Net pressure is generated by 39, uniaxial compression molding The application of the molding, uniformly "handed over to the humiliation material 37, in other words, the liquid additive liquid S is at 3 pressures and 3 seas" and the island is transferred to the material material 3 7, so the armor 4 (210X297 mm) 496905 A6 ____B6___ 5 Explanation of the invention () The same effect as hydrostatic pressure can be obtained, regardless of the uniaxial application of pressure and whether the mixture 38 is uniformly compressed. Further, uniaxial compression molding is performed as before, so the excess liquid additive 39 in the mixture 38 is discharged through the gap defined by the die 30, the lower punch 34, and the upper punch 36. In other words, the upper punch 36 and the lower punch 34 are embedded in the die 30 and the clearance is narrower than the size of the raw material 37. Therefore, the liquid additive 39 seeps out through the clearance and the raw material 37 remains in the cavity. It is believed that a pressure of 30 MPa to 10 GPa is suitable for the third step. Finally, the lower punch 34 and the upper punch 36 are separated from each other, the die 30 is opened, and the mixture 38 is taken out of the die 30. Examination case A1: l0wt ·% titanium isopropoxide was added to 100wt ·% mixed raw material 37, and the raw materials consisted of 96wt ·% electrolytic copper powder (325 mesh size), lwt.% Ni powder (average particle size: 0.5 / iin) and 3wt.% Al203 powder (average particle size: OMyn) and thoroughly mixed. Then, a liquid additive 39 (30 wt.%) Consisting of 2 Gwt.% Acetone and 80 wt.% Ethanol was added to the raw material 37 and thoroughly mixed to form a mixture 38. In this example, titanium isopropoxide is deposited and coagulated on the surface of the tree-shaped electrolytic copper powder and the surface of the mixed raw material 37 by the liquid additive 39. Then, the mixture 38 is fed into the mold of the uniaxial compression molding machine shown in FIG. 3 and the cavity 32 is compression-molded under a pressure of 300 MPa. Printed by the Central Bureau of Standards of the Ministry of Economic Affairs. In this case, the clearance between the die 30 and the lower punch 34 and the upper punch 36 is 100-2GQuin, and the sliding surface of the upper punch 36 to the die 30 is polished. In the compression molding process, when the applied pressure is higher than 30MPa, excess liquid is added. 23- (Please read the precautions on the back before filling this page) A 4 (210X297 mm) 496905 Printed by the Central Standards Bureau of the Ministry of Economic Affairs A 6 _._ B 6 _ V. Description of the invention () Agent 39 flows out through the clearance between die 30 and lower punch 34 and upper punch 36. This flow confirmed that the pressure applied to the mixed raw material 37 by the liquid additive 39 was uniform. After the pressure was increased to 300 MPa, the mixture 38 was taken out from the uniaxial compression molding machine. In this example, it is necessary to remove the preform of the mixture 38 from the molding machine at a pressure of 10 MPa or less, so that the removal operation is extremely easy. The preform of the mixture 38 is then calcined. After calcination, A1203 and Ti02 finely dispersed ceramic molded parts were obtained. Although it is not easy to obtain a density of 95% or more in the sintered body, the density of the ceramic molded article in Experimental Example A1 was 99% or more, and no void was found. In addition to the boundary of Yu Ying, Ti (N, C) is also generated, so the H2 effect is not a problem. In addition, the mixed raw material 37 used was an atomized copper powder having an average particle diameter of 8 μin instead of electrolytic copper powder, and uniaxial compression molding was performed at a pressure of 3 GQ MPa according to the aforementioned formula. As a result, a good-quality ceramic molded part was also obtained. 0 hh Example A1: Only a mixed raw material 37 having the same composition as in Experimental Example A 1 was dried at 8 Q ° C for 24 hours. It was then fed into a uniaxial compression molding machine shown in Fig. 3 to mold a preform at a pressure of 30 OHPa. In this case, the internal pressure of the cavity 32 is high and a pressure of 50-100 MPa is required to remove the pre- * molded body from the uniaxial compression molding machine. It is therefore impossible to remove the preform without causing deformation problems. All the preformed skeletons obtained by this method were destroyed. In Experimental Example A1, even after 100 shots, the mold 3G remained clean. No sticking phenomenon of the raw material 37 was observed, and the mold 30 A 4 (210X297 mm) (please read the precautions on the back before filling this page). • Line · 496905 A6 printed by the Central Bureau of Standards of the Ministry of Economic Affairs __Be_ V. Description of the invention () The appearance of the preform on the inner peripheral surface, the preform was taken out of the mold 30, even after a comparison with A1 After injection, the smooth surface becomes scratched or welded. Examination example A2 :. Appropriate amount of liquid additive 39 composed of acrylic resin emulsion, ammonium alginate and water-soluble phenol resin. 39 mixed with 9Gwt ·% silicon nitride, 5wt ·% alumina and 5wt.% Yttrium oxide. In the raw material 37, the average particle diameter of the raw material was 1.2 μm, and water was added at a ratio of 50 parts by weight to 100 parts by weight of the raw material 37. Wet mix in a ball mill for 24 hours. The resulting mixture 38 was degassed at 70 ° C. for 48 hours and then dried and ground to obtain a particle size of 30 mesh. In this way, the water content of the ground mixture 38 is controlled to 18-21% by using a humidistat and a water sprayer, so that a preformed mixture 38 is prepared. This mixture 38 has a doughy feel when rubbed with fingers. Then the mixture 38 was preformed under uniaxial compression molding under the pressure of 2G0MPa, with a size of 8QX 3GX 40m. The 30 preforms molded in this way were subjected to layer daytimes, and no cracks caused by layer S were observed. After dewaxing each preform at 65Q ° C, sintering of non-capsules was performed at 250 ° C at 175Q ° C for 2 hours. Generally speaking, when the preform is released and calcined by pressure sintering, the preform is crooked; or when the preform has a large difference in shape, it deforms, and a variety of molding defects can not be observed by visual inspection, and it is easy Cracks or breaks appear. However, taking the aforementioned preform as an example, only one of the 30 preforms has small cracks. The results were excellent. hh age example A2: Only mixed raw materials 37 with the same composition as in experimental example A2 are used in ball mill nail 4 (210X297 mm) (Please read the precautions on the back before filling this page) • Installation · • Line · 496905 Ministry of Economic Affairs Printed by the Central Bureau of Standards A 6 __B 6_ V. Description of the invention () After the machine is wet-mixed, it is dried at 7G ° C for 48 hours and then ground to a size of 30 mesh. The raw material thus ground was subjected to uniaxial compression molding under the same conditions as in Experimental Example A2 to obtain a preformed carcass. In this example, in 29 of the 40 preforms thus molded, cracks due to lamination were observed to cause defective molded products. In addition, when the preform was sintered under the same conditions as in Experimental Example A2, cracks and deformation caused by the daytime appeared on all the sintered S. Hereinafter, a second specific example of the present invention will be described in detail. In the method for producing a molded part according to this specific example of the present invention, a liquid additive is added to a powdery mixture to obtain a mixed raw material. The composition of the liquid additive is alcohol such as ethanol and 2-propanol, ketone such as acetone, and arene such as benzene. At least one of toluene, xylene, alkane such as hexane, and fluoroalkane, and water is added at a ratio of about 5-40 parts by weight / 100 parts by weight of the powdery mixture. If the ratio is less than 5 parts by weight, the flowability of the powdery mixture cannot be improved. In addition, in the initial stage of injection molding, the hydrostatic pressure application conditions could not be achieved, and the voids were blocked by the powdery mixture particles, in other words, they were blocked by the plastic deformation of the ballasting material, so they filled the discharge path of the liquid additive. Conversely, if the ratio is higher than 40 parts by weight, the excess liquid additive is separated when the pressure is applied, the final component is dispersed and suspended in the liquid, and then flows out of the mold through the boundary between the fixed mold and the movable mold or through the HIP vent Outflow. In addition, when the ratio of the liquid phase exceeds 4Q parts by weight, separation of components, particle size, etc. may occur during mixing of the components. Because liquid additives are compared with conventional low viscosity additives (that is, organic compounds such as petroleum paraffin and phenol resins, the addition ratio of which is 2G-50wt.% Of the total weight of the mixed raw materials) has low viscosity, in other words, high viscosity (please read the note on the back first Please fill in this page again for matters) • Binding, binding, • thread, 曱 4 (210X297mm) 496905 Printed by the Central Bureau of Standards of the Ministry of Economic Affairs A6 ___B_6_ 5. Description of the invention () Fluidity, so the mixing ability with powdery raw materials becomes higher . Therefore, it is possible to densely mix the mixed raw materials without heating the kneader and the mold for feeding the mixed raw materials, or the liquid additives and the mixed raw materials themselves in advance. The densely mixed raw materials thus injected are injected into the mold and maintained under the hydrostatic pressure by applying pressure. Thus, under the conditions of hydrostatic pressure application, pressure is transmitted through the liquid phase. Although friction and bridging between particles are caused by the end of powder particles being connected to each other, the phenomenon results in uneven pressure dispersion and high pressure is required today, but in this case, the pressure can be transmitted uniformly under the static pressure of the liquid skull. Therefore, heavy objects can be molded. In addition, when the internal pressure of the mold rises to a certain threshold or higher, the hydrostatic pressure in the mold is applied to break the sputum, in other words, the liquid mixture in the mold is broken through the liquid phase, so it is discharged through the k port of the mold or other clearance. Excess liquid it. After the excess liquid is discharged, the mixed raw materials are kept in the plastic deformation of the powder, so-called entanglement, so the liquid additive content is about lwt ·% to less than 5wt.% For metal molded parts, or 3wt. For ceramic molded parts. % To less than 15 wt.%. Furthermore, since excessive liquid additives are discharged from the molded article, defects or embrittlement caused by liquid sputtering or evaporation in the subsequent drying step can be avoided. Moreover, since a proper amount of liquid additive remains in the molded part and excess liquid additive is discharged, there is no need to perform a long dewaxing process, that is, a process of removing unnecessary liquid additives composed of organic compounds before calcination. . It is believed that due to the contact between the mold and the raw material through the liquid phase, in addition, compounds with excellent cleaning power, such as "Flonon sol (containing fluorine), are contained in the liquid additive, so the mold is often kept clean without any raw materials welded on the mold or held. Drag on the mold.

Description of the invention () High-quality preformed crossbones. In this way, ceramic molded parts obtained by calcining high-quality preforms with a small surface roughness can have the desired quality. In the following, the following examples will be used to illustrate the examples of the present invention. Fen Luo Example M: The copper powder was decomposed by weighing -325 sieve, and the average particle diameter was 2μπ. Aluminum powder, -325 mesh titanium powder, and -325 mesh metal aluminum powder, the proportions of which are 98.3 parts by weight, 0.8 parts by weight, 0.5 parts by weight, 0.3 parts by weight, and G.1 parts by weight, and a powdery mixture is used as a raw material. . Then, a liquid additive consisting of 80vqI% ethanol and 2Ονο 1% 2-propanol was added to the powdery mixture at a ratio of 12 parts by weight to 1QG by weight of the powdery mixture, and mixed until densely mixed, thereby obtaining a mixed raw material. The mixed raw materials were then injection-molded using an injection molding machine under a pressure of 300-2,000 kg f / cin2, thereby obtaining a preform. The respective sizes of the obtained preforms were 18EΠ wide and 80m long. Then, the preform was dried at 1GGt: 32 hours, and the amount of the liquid additive remaining in the preform was calculated from its weight before and after drying, and the density of the preform was measured from the amount. For each preform, the relationship between the water content and the pressure applied during injection molding is shown in Fig. 4, and the relationship between the density and the pressure applied at this time is shown in Fig. 5. . Then use a sintering furnace to heat the preform separately at a rate of 15 ° C / min and hold each at 25 0 ° C, 35Q ° C and 65 ° C for 30 minutes, and then maintain it at 950 ° C for 30 minutes. It was maintained at &gt; 0, 0 ° C for 30 minutes and 1,050 ° C for 2 hours, thereby obtaining a sintered body as a ceramic molded article. For individual ceramic molded armor 4 (210X297 mm) (Please read the precautions on the back before filling out this page) • Equipment · 496905 Printed by the Central Bureau of Standards of the Ministry of Economic Affairs A6 __B ^ 6_ V. Description of the invention () Under the atmosphere Sintering was performed for 1 hour, thereby obtaining a ceramic molded article. For individual ceramic molded parts, the relationship between density and the pressure applied during injection molding is shown in Figure 1. The ceramic molded parts thus obtained are each subjected to thermal iso-angle compression (hereinafter referred to as "HIP"), in view of making it into a denser high-strength product. The ceramic molded part was first formed into a size of 28 × 8 × 72 μm. The object thus produced was placed in a stainless copper pouch. The capsules were degassed and then vacuum-sealed, so that the ceramic pieces were subjected to HIP at 200 ° C for 30 minutes at 600 ° C. Measure the density of ceramic parts after treatment. It was found that those obtained by sintering at a pressure of more than 200 kg f / cm2 almost indicated that the true density was at least 97% of the theoretical value. It is believed that under the injection conditions of the prior art, the obtained preform needs to be heated to 6QG ° C in order to completely evaporate and remove low-viscosity additives such as petroleum paraffin and phenol resin. Such additions do not improve flowability and filling properties. When the preform is heated to 600 ° C and then subjected to a dewaxing process, the additive reacts with the aluminum contained in the preform as the bulk metal. Therefore, injection molding cannot be performed using aluminum as a raw material. Therefore, the raw materials are obtained by uniaxial compression molding or extrusion in the conventional technology, and the obtained raw materials are cast to form the raw materials. In addition, it was found that if no additives were added, the whiskers would agglomerate, so it was difficult to fill the raw material into the mold, and thus it was impossible to obtain a molded part. That is, in the method for manufacturing a ceramic molded article according to this embodiment, it is easy to obtain a ceramic molded article using aluminum 'as a raw material, and to receive HIP after injection molding.

As for the liquid additive, 20% by weight / 1QQ by weight of the powdery mixture is added with pure water, and the honing machine is wet-mixed 24 hours. The resulting mixture is degassed under reduced pressure to adjust the water content to 2Gwt.%, Thereby obtaining a mixed raw material. The mixed raw material is mixed by a kneader to obtain a mixed raw material at a pressure of 30D-2,0Q0.... The injection molding machine is used for injection molding to obtain preforms. Then the obtained preforms are dried and then calcined to obtain ceramic molded parts, and the density is calculated respectively. Figure 8 illustrates the pressure applied to the density of each ceramic molded part during injection molding. As for the comparative example, by using the same experimental example B3 The powdery mixture is used as the mixed raw material, that is, by weighing the average particle size (KSiUDl's master chemical silicon powder, the average particle size is G. 4 am, yttrium oxide powder, and the average particle size is 0.6 / in alumina powder). And lanthanum oxide powder with an average particle size of 1 M m so that its proportion # is 89 parts by weight, 5 parts by weight, 4 parts by weight, and 2 parts by weight. A powdery mixture is obtained by adding 30 vol% resole resin and 70vqI% petroleum paraffin.

Therefore, a preform M is obtained. This process cycle is controlled to 40 seconds, including the pressure residence time.

Therefore, it can only be molded in a narrow pressure range. _ * Printed by the Central Bureau of Standards of the Ministry of Economics, please read the notes on the back first. Fill in the line of this page again. In addition, in Experimental Example B3, cracks were generated in the ceramic molded article at any pressure of 1,800 kg f / cm2 or more. It is understood that under any pressure above this limit, the hydrostatic pressure application conditions are broken, and the particles collide with each other, so a large amount of residual stress is released during the calcination process. In addition, it is also necessary to understand the pressure below 700 kg f / cm2 in Experimental Example B3. When injection molding is performed next, the moment between particles becomes large due to the separation, so it cannot be effectively sintered. This can be observed when the ceramic molding is produced in Experimental Example B3. The wax and sintering method are useless, and the temperature range that allows the ceramics to be deeply molded is widened. The third preferred embodiment will be described in detail below.

When the electrode tips used for welding were analyzed, it was observed The degree of diffusion of the depleted metal component of the two electrode tips of the aforementioned Xianyu Institute is ¥ /. The metal component diffused in the electrode tip-reacts with the electrode tip component to form an alloy or a solid solution. ... In this way, the resistance of the electrode tip increases, and the distal end of the electrode tip generates heat. Therefore ...-..... The durability and corrosion resistance of the electrode tip need to contain at least one component in the material constituting the electrode tip, which can prevent the metal component from diffusing out of the electrode tip in advance and generate a solid solution. In other words, as an alloy group including copper as the main component At least one component selected from the group consisting of Cr, Ni, Co, Fe, etc. can be added to strengthen the strength and prevent metal components from being blended from the metalworking; add selected from Zn, A 1, Si, B, P, Hn, Ho , W, V, Nb, Ti, Zr, Hf, Ca,.

It is believed that all the aforementioned added components will suddenly increase the resistance of the electrode tip. To make electrode tips containing these components practical, it is necessary to use alloy components in an amount of up to 50 wt.%.

The new alloy thus produced can increase the resistance of the sample, thereby increasing heat generation and eventually oxidizing the distal end of the sample. Therefore, the heat generated on the sample rises again for two times, so that the molten Zn is adhered to the distal end of the electrode tip sample, and an insulating layer is generated by heat generation with oxidation. • »Results show that discharges due to migration corrosion are generated to a considerable extent.

Hereinafter, the fourth preferred embodiment will be used to explain the ceramic molded article of the present invention and its manufacturing method in detail. As shown in Examination Example c, the welding electrode tip of the ceramic molded article is roughly put to the user, and an oxide is formed on the electrode tip after use. In order to promote the durability and corrosion resistance of the electrode tip, it is necessary to include at least one component in the material of the electrode tip. Rather, the component can prevent the metal component from diffusing from the electrode tip working piece in advance to generate a solid solution. In other words, copper powder having a dendritic structure and being the electrode tip body metal is mixed with at least one oxide powder, sulphur powder or metal powder, and the particle size of these powders is small enough to fill the voids of the dendritic knots. The reaction initially reacted, and a part of the oxygen was generated in time. At this time, such a component causes the metal or the master to diffuse, and the chloride itself turns into an elemental metal. The chlorine released at this time oxidizes the active metal to produce ceramic particles. In addition, the deposited ceramic is used to connect the substrate to the ceramic, thereby producing a ceramic molding metal. In other words, ceramic particles are densified by sintering.

Addition of ceramics can increase the amount of electricity and electrolytic corrosion between granules and electricity. (Please first— | Mist 1 Yan Yi r ......: this page) ································ 5] The ceramic mold according to the present invention will be described in detail with reference to the accompanying drawings. In the ceramic molded article manufacturing method of this specific example of the present invention, electrolytic copper powder is used as a main component so as to provide copper having a high electrical conductivity as the bulk metal. However, Cu-Cr alloy is obtained by adding chromium powder due to low copper hardness. The strength of this alloy's organic maple is expressed as tensile strength% 强度 45kg f / cm2, due to its strong interatomic force. In addition, since it is low, its conductivity is 7Q-8Q% of copper simple substance. Less heat is generated from the surface in contact with the weld metal. Printed by the Central Bureau of Standards of the Ministry of Economic Affairs. However, when the aforementioned alloy is used as the electrode material to weld the galvanized weld metal, metal components other than the alloy component such as Zn and Fe easily penetrate into the crystal structure of the alloy. The components in the working atmosphere oxidize oxygen and generate enlarged oxides, so the crystal structure is brittle, and the alloy cracks and finally welds with the weld metal. Therefore, in this specific example, we want to avoid the phenomenon that leads to welding. Without reducing the conductive ratio of the alloy, fine chromium powder can be penetrated into the electrolytic copper powder and then a formazan 4 (210X297 mm) 496905 A6 B 6 V. Invention Explanation () It is made into ceramics by ★ Ministry of Standards M, so the crystal structure is densified to prevent different penetration of metal components. In this way, pure unoxidized powder can be used in ceramic production. In addition, the raw material powder is mixed to be plastically deformed by compression molding before the porcelain is formed, so that the particles of the raw material powder are adhered to each other. Subsequently, a part of the surface is oxidized to form an oxide film of the order of 0.01 to 0.01 μm. The reason for the formation of such a partial oxide film is that when the total surface of the raw material powder is covered with the oxide film, the subsequent sintering effect is hindered, so that the densified ceramic cannot be obtained. In addition, thicker oxide films than 0.1 Glum can prevent sintering. Conversely, an oxide film thinner than G. Q 0 1 a id hinders the formation of chromium oxide and the growth of the oxide film, so ceramics cannot be successfully produced and the desired effect cannot be achieved. The oxide film formed on the surface of the preformed constituent particles accumulates on the perimeter of the crystal grains at the final stage of sintering, and at the same time, it contributes to the oxidation of chromium and thus sintering according to the following reaction formula. 3CuO + 2Cr = 3Cu + Cra〇3 (+ Cr02) (+ CrO) In order to form an oxide film on the surface of the particles of the preform, the preform is in the atmosphere. At 100-3G0 ° C, preferably 1 3 0- 25 0 ° C heat treatment. After the heat treatment, the preform is sintered in a nitrogen atmosphere at a flow rate of 1G-3 0 Qm Ι / min in order to remove the adsorbed oxygen from the system before sintering and make the gas film uniformly formed on the particle surface. The higher flow rate than 30Oml / iDin makes the temperature distribution in the furnace wider and the results cannot be completed uniformly. On the contrary, the flow velocity is lower (please read the precautions on the back before filling in this page) • Assembly · • Order · Thread · A 4 (210X297 mm) -41-496905 A 6 、 _BJ__ V.

Sintering is performed at a temperature range of 950-1, 0 65 ° C for at least 30 minutes, but at most 6 hours. · Temperatures below 95G ° C make it difficult for sintering to proceed smoothly. Conversely, a temperature higher than T, Ό65Ί〇 will cause the sintered body to transform into If and evaporate to remove copper -_- components. The evaporated copper then solidifies and destroys the ceramic molding, which can cause injury to workers. The temperature must be set within the aforementioned range in advance. Hereinafter, this specific example will be described in detail by the following experimental examples with reference to the drawings. Experiential Example KI: A powdery mixture is obtained as a raw material by weighing the following components: electrolytic copper powder with an average particle size of 44 as the main component generating bulk metal, and chromium powder with an average particle size of Q.8 um as an additive component, The total weight of the powdery mixture is 98.5wt ·% and 1.5wt ·%, respectively. The obtained powdery mixture was added with ethanol, the mixture was wet-milled and dispersed in a ball mill, and chromium powder was mixed into electrolytic copper powder. Then, the ethanol content was adjusted to about 12-13%, and the adjusted powdery mixture received plastic deformation. The deformed powdery mixture was then uniaxially compressed into a 2 2 X 2 2 X 7 5 · size preform.

The preform thus obtained is dried at 80 ° C for 4 hours and then subjected to heat treatment at 110 ° C in the atmosphere for 1 hour and at 2 1G. For 4 hours, a gas film of the order of OG 01-0.0 1 / i id was thus formed on the surface of the particles constituting the preform. The preform after the treatment is at a speed of 1G ° C / m in.

'The sintering density of the sintered body was found to increase the hardness and the number of welding times. The ceramic molded article and manufacturing method of the present invention will be described in detail later by taking a sixth preferred specific example. In the method for manufacturing a ceramic molded article according to this embodiment of the present invention, a Cu-Cr alloy in which chromium powder is added to electrolytic copper powder as the bulk metal is used. However, when this alloy is used as an electrode material to weld galvanized metal, metal components other than the alloy components such as Zri and Fe easily penetrate into the alloy crystal structure. Different metal components are oxidized with oxygen in the working atmosphere to generate amplification. As a result, the crystal structure becomes brittle, the alloy cracks, and finally welds with the weld metal. Therefore, in this specific example, it is desired to avoid the phenomenon that will lead to welding without reducing the electrical conductivity of the alloy, so that the fine chromium powder penetrates into the electrolytic copper powder, and then the resulting mixture is sintered in an inert gas atmosphere such as m gas, and then chromium A nitride layer and a masterbatch layer are formed on the surface, so as to increase the surface ceramic particles corresponding to the deposition of chromium, thereby preventing the penetration of different metal components. Chromium is added in a composition range of at least 0.4 wt.% Up to 3.0 wt.%. An amount greater than 3 · Gwt ·% will sensitize the grain perimeter, so the chromium oxidation progresses to a greater extent than required, and intergranular corrosion occurs above chromium.

Sulfur residue exceeding G.lwt.% Can suppress the densification of the obtained sintered body.

The metal is made of copper plates coated with 45g / in2 zinc on both sides, with a thickness of 0.8 ππη. The next test is the continuous spot welding ability and welding performance of the weld metal. For comparison, an alumina-dispersed copper containing 0.8 wt.% Alumina was used. The results are shown in Figure 12. It is clear from Fig. 12 that the number of possible spot weldings in this example is 2,500 points and that of the comparative example is 900 points. Therefore, the number of consecutive spot welding may be improved to about 278% and the welding time may be reduced to 1/5.

It is also necessary to understand that it is better to use ethyl fibrinolysin, that is, liquid skull material, as masterbatch material. Experiential Example F3 Use powdery raw materials such as Experimental Examples F1 and F2, in which ceramic moldings with chromium powder added at a ratio of 0.8wt.%, 1.4wt.% And 2.4wt.%, Respectively, are based on the corresponding groups of chromium and other additive components The corresponding composition of the inert gas and the additive gas generated in the inert gas atmosphere is obtained; the composition range and composition are shown in Fig. 15a, and the obtaining method is shown in the experimental examples F1 and F2, but only the sintering time is reduced to 30 minutes .

Description of the invention (). It is thus judged that the surface of the raw material powder can be cleaned by adding NH3, C0 and / or 112 into the inert gas. In addition, in terms of sintering time, Experimental Example F2 in each case required 60 minutes to sinter the preform. In contrast, in each of the experimental examples, although the sintering time was shortened to 30 minutes, the desired effect was obtained. Therefore, it is judged that the nitriding and carbonization efficiency is strong, which is helpful for sintering. Hereinafter, the ceramic molded article of the present invention and a method for manufacturing the same will be described in detail by using a seventh preferred example. During the manufacturing process of the ceramic molded article of the present invention, the obtained Cii-Cr alloy is welded when the zinc-plated welded metal and aluminum alloy are welded. Therefore, in this specific example, in order to avoid the welding phenomenon without reducing the conductive pseudo number of the alloy, the chromium / aluminum and titanium fine powder is diffused into the electrolytic copper powder, and then the obtained mixture is sintered in an inert gas atmosphere such as nitrogen. On the surface of chromium, a nitride layer and a compound layer are formed. By depositing 1¾ on chromium, the surface ceramic particles are increased, and aluminum is oxidized to Al203, and titanium is oxidized to Ti02 and f.

TiO, and nitriding and mastering titanium into TiN, TiC and Ti (C, N) thus increase the ceramic particles, which can prevent the penetration of different metal components. The Central Bureau of Standards of the Ministry of Economic Affairs has added chromium, aluminum and titanium in a composition range from at least G.4 wt.% To at most 3.0 wt.%, From at least 0.05 wt.% To at most 1.2 wt.%, And from at least 0.003 vft. % At most l.Ovft.%. Chromium greater than 3.0wt.% Will cause the oxidation of grain-peripheral sensitized chromium to a degree greater than required, so intergranular corrosion and other phenomena appear above it; in addition, the electrode material composed of this alloy will over time While deformed. Therefore, the addition of chromium in this amount does not substantially achieve the desired effect. On the other hand, the addition of chromium below Q. 4 wt.% Is also without -53- (Please read the precautions on the back before filling this page) A 4 (210X297 public love) 496905 A6 printed by the Central Bureau of Standards of the Ministry of Economic Affairs __JB6__ V. Description of the invention () ^ ^ The method is effective. In the case of aluminum, amounts below 0.05 wt.% Will result in failure to achieve the desired effect. On the contrary, an amount exceeding 1.2 wt.% Will increase the alloy resistance, so that the alloy cannot be put into practical use. At the same time, in the case of titanium, adding less than 0.03 wt.% Will lead to the failure to achieve the desired effect, and more than 1.0 wt.% Will also make the alloy larger, so the alloy cannot be put into practical use. To provide an inert gas atmosphere, use a mixture of nitrogen and argon and / or hydrogen as the inert gas. The cost of using argon alone is high, but the use of hydrogen alone has the danger of explosion. The reaction efficiency can also be promoted by adding monoxide, ammonia and / or the like into the inert gas skeleton. In view of cleaning the surface of the oxidized powder, promoting the nitriding effect of chromium and titanium, and using chromium and titanium for sulfonation, the proportion of masterbatch-containing materials is at most G.lwt.%. A master residue exceeding 0.1 wt.% Will suppress the densification of the sintered body formed. At the same time, from the standpoint of compacting and dispersing, it is necessary to add masterbatch materials in the aforementioned range. Palace test example G1: The powdery mixture as a raw material is provided by the following, the electrolytic copper powder with an average particle size of 44 am is weighed as the main component of the bulk metal, and the chromium powder with an average particle size of 1.6um is averaged.

Therefore, the enhancement of nitriding and mastering functions is so helpful for sintering. Hereinafter, a ceramic molded article according to the present invention and a manufacturing method thereof will be described in detail by using an eighth preferred specific example. The Cn-Ci: alloy obtained during the manufacturing process of the ceramic molded part according to the present invention is welded when the galvanized weld metal and the aluminum alloy are welded. Therefore, in this specific example, it is desired to avoid the welding phenomenon without reducing the conductive pseudo number of the alloy, so that chromium, aluminum and titanium fine powders diffuse into the electrolytic copper powder to form ceramics, thereby making the crystal structure denser to prevent different metal groups. Percent penetration. Ceramics are produced using purified powder without chlorination.

Printed by the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back first) (Fill in this page) The reason for the formation of this partial oxide film is that when the total surface of the raw material powder is covered with the oxide film, the subsequent sintering effect is hindered, so that dense ceramics cannot be obtained. In addition, it is thicker than Q. 0 1 ν id The oxide film will hinder sintering. Conversely, an oxide film thinner than 0.001 α id will hinder the generation of chromium oxide and the growth of the oxide film. Therefore, ceramics cannot be successfully produced and the desired effect cannot be achieved. The oxide film formed on the surface of the particles of the preform.

Accept heat treatment. After the heat treatment, the preform is sintered in a nitrogen atmosphere at a flow rate of 10-30Ginl / iDin in order to remove the adsorbed oxygen from the system before sintering and make the oxide film uniformly formed on the particle surface. Than 3QQml / The higher flow rate of iDin makes the temperature distribution in the furnace wider and the result can not be completed evenly. Conversely, the flow rate below 10inl / min cannot achieve the desired effect. Sintering is performed at a temperature range of 95Q-1,0 65 ° C for at least 30 Minutes, but up to 6 hours. Temperatures below 95G ° C make it difficult for sintering to proceed smoothly. Conversely, temperatures above 1, 0 65 ° C will transform and deform the sintered body and evaporate the copper components.

Description of the invention () 3Cu (Cu20, copies ) + 2Cr = Cr2〇3 + 3Cu (6Cu, parts) 3Cu0 + 2Al = 3Cu + Al20a 2CuO + T i = 2Cu + T i〇2 It can be seen that electrons appear above the copper particles that generate an oxide film by heat treatment Migration, and chromium, aluminum, and titanium are oxidized by sintering, and aluminum and titanium thus lead to improved continuous spot welding capabilities. The FeCUXHCl mixed solution etched the sample and observed the crystallinity of the sample. As a result, the comparative example sample was fibrous, and a dense crystal lattice was observed on the experimental example sample. The observation of the structural formula using an electron microscope revealed the deposition of ceramic components on the copper grains. It is necessary to understand that this ceramic combination is deposited by oxidation during the production of chromium ceramics. In addition, the adhesion between the deposited components and the copper grains was observed. It is believed that this adhesion is a chemical bond and is accompanied by diffusion. _ Use micro-focus X-ray analysis to define oxides and define Cr203, Ti02, A1203, and small amounts of Cr02 and TiO, respectively. Although metal aluminum powder and metal titanium powder are used as the raw materials of aluminum and titanium oxide in this experimental example, it can also be added in the form of oxide from the beginning.

Description of Invention () Individual preforms. The preform thus obtained was dried at 80 ° C. The preforms were then processed according to the first to 25th process conditions shown in Fig. 10a to obtain ceramic molded parts. The sintered bodies 1 to 35 thus obtained were used as samples to perform experiments *--... *--Test of Example H1. The results are shown in Figure 22. Judging from the results of the test as a whole, when the amount of chromium is at least G.ht.% to at most 3.Gwt.%, Preferably at least 0.8wt.% To at most 2.4wt, the amount of aluminum is 0.05wt.% Up to 1.2 wt.%, Preferably at least 0.1 wt.% To at most () .8 wt ·%, and the addition amount of titanium from at least 0.03 wt.% To at most 1.0 wt.%, Preferably at least 0.05 wt. In the range of.% Up to 0.6wt ..%, the obtained ceramic molded article is suitable for practical use. Hereinafter, the ceramic molded article of the present invention and its manufacturing method will be described in detail with reference to the ninth preferred embodiment. In the conventional uniaxial compression molding, the movement process of the individual particles is complicated, due to the friction resistance between adjacent particles and / or the size and hardness of the particles, or the inner cavity of the molding device 40 defines the cavity 44. Caused by differences in materials and / or surface roughness, as shown in Figure 26. It is thus difficult to apply uniform pressure to the raw material 45 composed of particles in order to obtain a preform having a uniform density throughout. Therefore, an attempt is made to apply excessive pressure to the raw material 45 to plastically deform the raw material 45 into the state shown in Figs. 24 and 25 to increase the density. Even in this case, * the low-density portion and the high-density portion remain in the preform. When the preformed slab thus obtained is calcined to obtain a ceramic molded part, the gas 45b between the particles 45a of the residual raw material 45 is discharged through the path generated by the particle space. This interparticle space is compressed by the powder when the particles are sintered and densified.

As shown in Figure 25, in the high-density part of the compressed raw material 45, the residual gas 45b is entangled by the particles 45a, so a so-called closed void is generated, and The gas skull 45b is closed in the gap and cannot be discharged. In addition, while the preform is slowly sintered, the volume of the residual gas 45b gradually decreases until the densification pressure during sintering reaches the internal pressure of 逹 and the residual gas 45b. However, it is also difficult to completely eliminate the closed void. -F- Conversely, in this experimental example, 'when% ^ liquid additive 49 is added to the raw material \ mixture 50 in powder form, it is axially-molded via the wall ( group The gaps 42 a to 42 b of the molded cavity 44) and the punches &amp; make the vertices and / or edges of the particles cross-linked to each other, so that the individual particles of the shame 45 can form a bridge 64. Then, the gaps of the bridge 64 are passed through The excess liquid additive 49 is removed, and at the same time, the raw material 45 is molded into a preform in the pressure range of the plastic deformation of the raw material 45 through the application of liquid static pressure. As a result, a preform having a uniform density is obtained. In addition, the remaining gas between the particles It can be discharged during sintering. Case T: In the ceramic molding method of Experimental Example I, the molding device 4 G shown in Fig. 26 is used. First, the liquid additive shown in Fig. 23 is 4 9 Add the corresponding 1st to 7th raw materials in powder form (as shown in Figure 23) and mix to obtain the respective mixture 50. i Then the mixture 50 is filled into the respective mold cavities 44 of the molding device 40. This.xilfcy The gaps 42a to 42d defined between the forming die cavity 44 ^ 1 ^ and the lower punch 45 and the upper punch 48 are shown in Fig. 23. The lower punch 46 and the upper punch 48 and the die are shown in Fig. 23. The sliding surface of 40 rooms is light.

Description of the invention () Then began to compress each mixture 50 by borrowing the punch 46 and the upper punch 48. As shown in Figure 27 during the preform molding process in this experimental example The relationship between the applied pressure and the density is indicated by the solid line 66. The custom of the prior art during the molding of the preform (which does not contain any liquid additives) is indicated by the solid line 68. In addition, the amount of excess liquid additives discharged The relationship between the pressure and the applied pressure is indicated by the solid line 70. During the rough load process indicated by A in Fig. 27, the particles of the raw material 45 constituting the mixture 50 are independently dispersed in the liquid additive 49, as shown in Fig. 28 (a) Show. Further pressure is applied to move the particles 45a and discharge excess liquid components, so the compression process of the particles 45a is converted to the density transfer process B until the edges of the particles 45a of the raw material 47 and / or the vertices are joined to each other, as shown in FIG. 28 ( b) shown. When transferring to transfer process B, the pressure is usually 750 kg f / cm2. Printed by the Central Bureau of Standards of the Ministry of Economic Affairs The lower punch 46 and the upper punch 48 in the transmission process B are restricted by the reaction force of the respective contact surfaces 46a, 48a from the mixture 50, as shown in Figure 26. As a result, the contact surfaces 46a, 48a are extended toward the die 42, so that the gaps 42a to 42d are narrowed. Thus, in terms of the fluidity of the particles 45a constituting the mixture 50, the part of the particles located in the center. 45a has a higher fluidity than the other part (located near the mode 4 2) of the particles 45a, which is attributed to the mode 42 The frictional force between the wall surface and the particles 45a is larger than that of the interlocking particles 45a. In addition, the maximum stress is applied to the edges 60a to 60d of the mixture 50 due to the aforementioned two factors. As a result, the particles 45a are densified from the edges 6Qa to 60d. With the increase in pressure, some particles 45a that have been connected to each other due to densification are finally at the edges 60a to 60d -66- Please read the precautions on the back before filling ✓ A 4 (210X297 mm) 496905 Central Ministry of Economic Affairs Printed by the Bureau of Standards A6 B 6 Fifth, the description of the invention () and the wall of the mold 42 to generate a bridge 64 (Figure 31). The bridge 64 thus generated prevents the particles 45a constituting the mixture 50 from flowing out of the cavity 44. In addition, the hydrostatic pressure can be maintained by an appropriate amount of the remaining liquid additive 49. Therefore, the contraction process of the particles 45a is converted into a dense load process C. It is believed that the pressure applied to the entire mixture 50 during this process is uniform. During the densification load process C (as shown by the solid line 66 in FIG. 27), the mixture is further densified by discharging excess liquid components while applying liquid static pressure within the pressure range in which the mixture 50 is plastically deformed. As a result, the preform molded according to this experimental example became uniform, and the density of each part was uniform. In addition, since the particles 45a are placed in the plastic deformation region, the particle gaps also remain in an open gap state. If a pressure higher than 1,5 GGkg f / cm2 is applied during the densification load C, the density of the rare preform will increase. At this point, the molding of the preform is completed. In contrast, in the prior art method, which does not contain any liquid additives and is indicated by the solid line 68, the pressure needs to be further increased to about 75, GGOkg f / cin2 (including the subsequent calcination process) in order to provide the desired density to the preform To complete the molding. According to the method of this experimental example, a preform can be obtained at a pressure of about 1 / 5C to 1 / 1Q0 of the pressure required by the prior art. The thickness of the preform obtained by the prior art method is at most about IGm. According to the method of this experimental example, a preform having a thickness of at most about 120 μm can be molded. '· Finally, the preforms obtained by the aforementioned methods were separately calcined to obtain respective ceramic molded articles. The compression conditions of each part of the preform obtained according to the prior art method are not uniform and have closed voids as shown in (d) of FIG. 28. Therefore, the strength of this preformed protection is insufficient. On the other hand, the preform A obtained in this experimental example 4 (210X297 mm) -67-

496905 m A 6 _B6_ V. Description of the invention The compression condition of the body has an open space as shown in Figure 28 (c). Therefore, the gas remaining inside the preform can be discharged, thereby eliminating any voids after calcination. Ceramic molded parts having high density can be obtained. According to the method of the present invention for the production of ceramic molded parts (as described above) ... due to compression,-•. Molding is performed using liquid additives under hydrostatic pressure conditions, so uniform pressure can be applied to the powdery mixture as a raw material, so A high-quality ceramic molded article having a uniform density and a small surface roughness can be easily provided by applying a small pressure according to a simple method. In addition, due to the high cleaning power of the liquid additive, the mold can often be kept clean, thereby achieving a significantly extended life. In addition, according to the ceramic molding method of the present invention, the wettability with the substrate can be improved, and interface bonding can be performed. Ceramic moldings are made by sintering. In this way, when ceramic molded parts are used as electrode materials, the metal-metal components in the work piece can be prevented from diffusing or penetrating into the electrodes, etc., and alloys or solid solutions can be formed with the metal components, and chlorides can be further formed, and obtained. Interparticle resistance, interparticle discharge, and reduction of matrix electrolytic corrosion. In addition, according to the manufacturing method of the ceramic molded article of the present invention, it can be obtained that the ceramic molded article has excellent mechanical strength and conductive pseudo number when used as an electrode material, and the service life of the electrode molded article can be prolonged, because Since the welding performance with the welding metal is reduced, and because the sintering efficiency is improved, electrode materials and the like can be easily obtained at low cost.
