Description of the invention (/) The present invention relates to an abrasive for ceramic gold steel grit, and its preparation method and tools made from the abrasive. In addition to fused corundum, the use of ceramic gold steel sand has become more and more, because the ceramic gold steel sand has a polycrystalline structure (polycrystal 1 ine structure) and shows good wear properties, while The machining of special materials (such as high alloy stainless steel) can greatly extend the life of the tool.丨 Rongjun-Gel method is a method widely used to make this kind of ceramic diamond abrasives, like transforming a sol with water-containing gasified bromide (usually gasified bromide hydrate) by adding acid into condensate The glue is dried, crushed and then sintered. Especially in the past ten years, there have been many attempts to use special processes (EP-B263810) or by adding materials to improve the properties of such abrasives. The method of adding materials can be classified as a nuclear generating agent (M. Kuraagaiand GL Messing: Con-tro1 led Transformation and Sintering of a Boehmite Sol-Gel by «-Alumina Seeding, J. Am. Ceram. Soe. 68⑼, 500-505 (1987)) or on the other hand is classified as a modifying ingredient. The latter affects the sintering process and the structure and properties of the final product in different ways. Modified ingredients used such as money, to, Ming, nickel, zinc (EP-B0024099), Shen B (EP-B 228856), iron vapors (EP-B 20 0487), rare earth metals (EP-B 293164 ), Lithium (ΕΡ-Δ 441640). Of course, some of these additives will have an important improvement in the properties of friction, but their value has a role in reducing quality due to widespread dispersion.

Description of invention (丄) Tradition In addition to the physical material properties such as the micro-abrasion of the gold sand abrasive, the life extension of the tool is also as important as the high stability of these two physical property values within a particle size range. The present invention is based on This knowledge was started. The purpose of the present invention is to prepare a gold-steel grit abrasive with only a small change in properties within the same lobe particles in addition to the general property characteristics (especially the hardness). Surprisingly, this kind of abrasive It can be achieved by adding tin. Therefore, the abrasive image of the present invention mainly containing ceramic gold steel grit contains tin as a sign, and its content is calculated as tin oxide to be 0.01% by weight or more of the final sintered product, with 0.1 weight % Is better, but not more than 5% by weight, and preferably not more than 1% by weight. It is currently known that addition recording can improve the hardness and fineness of particles, which has been confirmed by further confirmation. If the abrasive also contains lithium, the hardness and the uniformity of the product can be further improved, and finally other modifying ingredients such as Ming, az, feed, iron, and / or rare earth metals can be used. The surface of the product made by the example is broken, touched and polished, and its optical properties are tested to show a structure that is easily distinguishable from conventional products. Some large particles have a trapezoidal structure unique to oc-gasification bromide ( terrace structure) (Petzold / Ulbricht-Alumina andalum ina materials, p.83, Figure 7.14), small particles have a cumulative phenomenon, the average size ratio is at least 3: 1, usually greater than 5: 1. Most of the adjacent large particles (Almost finished gold in most cases) separated by a small particle. These smaller particle layers will form a continuous matrix, and the larger-a wooden paper correction standard rate (CNS) Λ4 says Grid (2 丨 () X297 Gongmeng―) (Please read the precautions on the back before filling in this page) Clothing · Order A7 B7 Printed by the Employees Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5. Invention Instructions (3) Particle embedding. Triangle between large particles The accumulation of small particles in voids covers at least a large range as if they are connected to each other through branches. What is quite different from the appearance of particles is the different composition, in which particles (crystals) that are morphologically distinguishable Contains a very high or low concentration of modifying ingredients, and the part polished by the worm is quite prominent. In this article, the particles refer to the forming units that can be distinguished from each other due to the obvious boundaries in the single part polished. , Also refers to crystals. In addition to its high hardness, the abrasive of the present invention is highly resistant to high thermal and mechanical loads, so if it is used in an abrasive belt with the abrasive of the present invention, it will greatly increase the per unit time In addition to the amount of material that can be worn away, a large cap can extend the life of the tool. The abrasive of the present invention can be used on a substrate as a component of bonded grinding tools in terms of abrasive blasting or lapping or as a loose abrasive. The abrasive of the present invention can be used in a qualitative and quantitative combination with other kinds of abrasives in all fields of application, and is more advantageous when mixed with high-hardness abrasive particles such as nitrated sand, tetragonal boron nitride or ore. In addition, the abrasive of the present invention can also be used as a matrix to incorporate one or more abrasives with different properties. The latter is achieved by mixing other abrasives into an intermediate (preferably sol or gel) in the preparation process of the abrasive of the present invention. In this process, it must be ensured that the tin-containing material is intimately mixed with other starting materials and finely dispersed in these starting materials. If the preparation process starts from a powdered starting material that has undergone calendaring and sintering, the tin-containing material is preferably added in the form of powder. This tin-containing material can also be in a liquid state and mixed into this paper. # MJfl 中 VALVE VALVE Biaohua (C'NS) Λ4 ^ Grid (210X297 public release) (please read the precautions on the back before filling this page) 312703 A7 B7 Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of the invention (). The material to be sintered or sprayed on the material to be sintered. If the dissolution-gel method is used and the tin-containing material is added to the starting material before the gel is generated so that the tin-containing material is already contained in the dispersion liquid (sol) that will form the gel, then it can achieve a fairly intimate mixing effect. This tin-containing material can be in a solid, finely divided, crushed state or in a solution. It has been determined that the dry gel produced by the method of the present invention has a property capable of withstanding high mechanical loads in comparison with the Wuxi method. This not only indicates that this method has a considerable modification effect, but also improves the crushing effect of the dried gel in terms of yield and the shape of the crushed particles. The addition of the starting material or intermediate physical tin oxide in the form of powdered Sn〇2 has been proved to be a particularly useful compound in the present invention, but other tin-containing materials such as tin salts can also be used. It is advantageous for this solution to contain 7-vaporized aluminum which is separated very finely and crushed if necessary. If further adding lithium (preferably mixed into the intermediate in any stage in the form of an aqueous solution of lithium salt), a particularly good result can be achieved. The lithium compound (preferably a lithium salt) should preferably appear in the sol in a dissolved state, and in the sol If it contains other modifying ingredients (especially those mentioned above), it is best to also exist in the sol in a finely separated solid state or in a state of dissolution, and these ingredients can also be added to another intermediate.

Description of invention () Age 0.01-0.4% Rare earth metal 0.1-2¾ In addition to the above, Sol-Ningjun The process steps of the method are not necessary to elaborate further because these steps can be performed using existing prior art, especially the steps described in the aforementioned patent documents. The starting material used is a kind of hydrogenated bromide, and it is preferably a boehmite type oxygen <aluminum oxide hydroxide, such as Condea-Chemi at Brunsbiitte 1. Various Disperal Oxidation Marks manufactured by e Company have proved to be very useful materials. After the addition of deionized water and nitric acid, a suspension is obtained. This suspension may be centrifuged as necessary to remove coarser components. It is best to add a nuclear generator (nucleus former) or -χ —oxygen dagger, and it is necessary to use this substance. 7-Gasification broth can be contained in the aqueous dispersion of nitric acid first, and this dispersion can be centrifuged in the same way. Mixing a certain amount of these dispersions with any modifying ingredients (preferably in the form of an aqueous solution or aqueous dispersion) to obtain a suspension, this suspension is converted to coagulation using nitric acid and / or its salts in the aqueous solution and then This gel was dried and calcined. The dried or burnt intermediate is crushed and classified as necessary. Then, the calcined intermediate is sintered, and finally the obtained abrasive is dripped and mixed to make a batch of grains having a uniform particle size. We have found that the use of lithium and the selective use of the aforementioned components but without tin can also achieve very good results, especially when 2% by weight of embedding (in the oxide state in the sintered product) is added. Although the technique of adding interest is already known (ΕΡ 0441640), this gasified substance contains clams in the sintered product is the most 7 · — ^ — (please read the precautions on the back before filling in this page) This paper is based on size; ^ Use net Minjia Biaoping ((^ $) August 4 specifications (210> (297 public Zhao) Ministry of Economic Affairs Central Standards Bureau employee consumer cooperatives printed 312703 A7 B7 V.
