品などとして実用化されているをはじめとして、その他
の分野でのこれからの実用化が期待されている。Conventional technology and its problems Fine ceramics are chemically stable, have excellent heat resistance, wear resistance, etc., and can also exhibit relatively high mechanical strength under optimal conditions, so they are currently used in electronic parts and machinery. In addition to being put to practical use as parts, it is expected that it will be put to practical use in other fields in the future.
しかしながら、セラミックスは、一般に機械による加工

常は脆性材料として靭性材料である金属と接合された状
態で使用される場合が多い。However, since ceramics generally lack machinability, it is difficult to mold and process parts with complex shapes, and it is difficult to form parts with desired shapes unless a plurality of pieces are joined together. Further, although ceramics are theoretically high-strength materials, for safety reasons, they are often used as brittle materials in a state where they are joined to metals, which are tough materials.
従来、セラミックスとセラミックスとの接合或いはセラ
ミックスと金属との接合は、主に下記の方法で行われて
いるが、いずれの方法にも、改善すべき問題点がある。Conventionally, joining of ceramics to ceramics or joining of ceramics to metals has been mainly performed by the following methods, but each method has problems that need to be improved.
（イ）高温高圧下にセラミックス相互またはセラミック
スと金属とを接触させて、両者の界面での原子の拡散に
より接合を行なうホットプレス法やＨＩＰ（ホット・ア
イソスタティック・プレス）法がある。(a) There are hot press methods and HIP (hot isostatic press) methods in which ceramics or ceramics and metal are brought into contact with each other under high temperature and pressure, and bonding is achieved by diffusion of atoms at the interface between the two.
この方法によれば、高強度の接合体が得られるものの、
接合時に材料がクリープ変形を起こして、成形不良を生
じやすい。Although this method yields a bonded body with high strength,
Materials tend to undergo creep deformation during bonding, resulting in molding defects.
また、ホットプレス法やＨＩＰ法で使用する装置類は、
高価であり、従って、必然的に成形体の製造コストも高
くなる。また、装置の制約上大型の接合体が得られない
という難点もある。In addition, the equipment used in the hot press method and HIP method is
It is expensive, and therefore, the manufacturing cost of the molded body is also inevitably high. Another drawback is that large-sized bonded bodies cannot be obtained due to equipment limitations.
（ロ）セラミックス上にＭｏＳＭｏ−Ｍｎなどの微粉末

合する方法（モリブデン−マンガン法が代表的なもので
ある）がある。(b) Fine powder such as MoSMo-Mn is applied onto ceramics, metallized at a temperature of about 1300 to 1700°C in humidified hydrogen or humidified forming gas, and then nickel plated on top of it, followed by brazing. For example, there is a method of joining using Ag.-, Cu alloy, Ag-Pd alloy, etc. (a typical example is the molybdenum-manganese method).
この方法は、接合工程が複雑であり、また貴金属を主成
分とするろう材を多量に使用するので、製造コストが極
めて高いという問題点がある。This method has the problem that the bonding process is complicated and the manufacturing cost is extremely high because it uses a large amount of brazing filler metal whose main component is a noble metal.

It has been found that it exhibits excellent effects as a bonding agent.
すなわち、本発明は、下記のセラミックス用接合剤を提

論可能である。The bonding agent for ceramics of the present invention is made of silicon oxide (Si
O2), manganese oxide, and cobalt oxide are essential components, and other oxides can be used in combination depending on the type of ceramic, bonding conditions, etc. For reasons such as stability and availability, MnO is preferred as the manganese oxide, and CoO is preferred as the cobalt oxide, but it is of course possible to use other oxide forms.

体のそれに近似する様に配合割合を調整する。The quantitative proportions of silicon oxide, manganese oxide, and cobalt oxide vary widely depending on the type of ceramics to be joined, the usage environment of the ceramic joined body, etc.
Normally, the ratio in the bonding agent (1 total %) is silicon oxide: manganese oxide: cobalt oxide = 20 to 79.9%: 20
~79.9%20.1~10%. The ratio of each component can be selected within the above range, but -
As a quantitative selection criterion, the blending ratio is adjusted so that the coefficient of thermal expansion of the bonding agent layer approximates that of the objects to be bonded.

がより好ましい。Furthermore, when joining different types of materials, the blending ratio is adjusted so as to alleviate residual stress caused by the difference in thermal expansion coefficients of the two wave joining materials as much as possible. Generally, if the amount of S i 02 is too small (in other words, if the number of times of MnO is too large), the strength of the adhesive layer itself may decrease, resulting in insufficient bonding strength. . On the other hand, if the amount of 5i02 is too large, not only will the melting point of the bonding agent become high, which is disadvantageous in practice, but also the amounts of other components will be relatively reduced, resulting in a bonded product with desired properties. will not be obtained. Further, when the Co content exceeds 10%, no particular improvement in effectiveness is observed. The particle size of the above-mentioned essential components and the following oxides in the present invention is preferably as small as possible, and when used in powder form, it should be 100 μm or less, and when used in sheet form, it should be 1 mm or less. is more preferable.
本発明接合剤には、必要に応じて、下記に例示する様な
各種の酸化物をさらに配合することが出来る。The bonding agent of the present invention may further contain various oxides as exemplified below, if necessary.

は、５〜２０部とすることが好ましい。Aluminum oxide (A1203) exhibits the effect of improving the strength of the bonding agent layer itself, so it is desirable to include it in the bonding agent of the present invention when the strength of the bonding agent layer is insufficient with only the above essential components. The upper limit of the amount of aluminum oxide to be blended is about 20 parts per 100 parts by weight (hereinafter simply referred to as "parts") of the essential components. When the amount of aluminum oxide exceeds 20 parts, the melting point of the bonding agent becomes high,
This makes joining work difficult. In order to significantly exhibit the effect of improving the strength of the bonding agent layer, the amount of aluminum oxide is preferably 5 to 20 parts.

。Group IA elements (hereinafter referred to as alkali metal elements) and II
Oxides of group A elements (hereinafter referred to as alkaline earth metals) are:
It is an effective component in adjusting the coefficient of thermal expansion of the bonding agent, making it possible to bond a wide variety of ceramics. That is, they are added to the bonding agent of the present invention when the desired coefficient of thermal expansion cannot be obtained only by adjusting the blending ratio of the essential components. Oxides of alkali metal elements and alkaline earth metals include Na20, K2O, Li2O, Cs2O, MgO1C
Examples include ab, Bad, SrO, etc., and one or more of these may be used. The amount used is 10 essential ingredients.
The upper limit is about 20 copies compared to 0 copies. When the amount of at least one of the oxides of an alkali metal element and an alkaline earth metal exceeds 20 parts, the proportion of essential components decreases, so that properties such as bonding strength may deteriorate.

化剤を０．１〜１０部程度程度する。That is, in zirconia ceramics, stabilizers (Y203, MgO
1CaOSCeO, etc.), but during the bonding process or when used at high temperatures in the bonded state, the stabilizer in the zirconia diffuses into the bonding agent layer, reducing its concentration, and as a result, the bonding agent This may cause deterioration of the strength of the layer. In order to suppress such diffusion of the stabilizer and prevent a decrease in strength, the amount of the stabilizer is about 0.1 to 10 parts per 100 parts of the essential components in the bonding agent of the present invention.

、酸化性雰囲気中で行なっても良い。When bonding ceramics to each other or ceramics to metal using the bonding agent of the present invention, for example, a powdery bonding agent or an organic binder is added to at least one surface of the materials to be bonded to form a paste. Apply a bonding agent or add an organic binder and place the bonding agent in the form of a sheet between the materials to be joined, overlap the two materials, and heat the adhesive to a temperature above the melting point (800 to 1200℃) of the bonding agent. Just heat it up. At this time, pressure may be applied as appropriate to ensure good adhesion between the materials to be joined and the bonding agent. In addition, the atmosphere during the welding operation is such that if one of the materials to be joined is metal,
It is preferable to carry out the process in an inert or reducing gas or in a vacuum, and if the materials to be joined are ceramics, the process may be carried out in an oxidizing atmosphere.
