It is reasonable to configure parts that require corrosion resistance with ceramics and other parts with metals, and this is necessary to compensate for the disadvantages of ceramics such as brittleness and high cost. Therefore, efforts are being made to develop a simple and highly reliable method for joining ceramics and metal.

はセラミックス部品が破壊に至ることもある。Although oxide glass methods using AI-, O-, and glass-containing glasses as brazing materials are known, they all have the problem of insufficient adhesive strength. The reason for this is that when metals and ceramics are brazed at high temperatures, the metal and ceramics shrink during the subsequent cooling process, and the shrinkage rate of the metal is significantly greater than that of the ceramics, resulting in large compressive stress. This can lead to destruction of ceramic parts in some cases.

However, even with this method, the drawback of weak adhesive strength cannot be overcome, and workability is also poor.

制御することにより調整できる。Substitution with metal ions such as Cu can be performed by mixing aluminosilicate powder and an aqueous metal salt solution. Specifically, a metal ion-substituted aluminosilicate is obtained by mixing an aqueous solution of a metal salt such as Cu (N Oa )- and an aluminosilicate powder or dispersion (slurry) with stirring. Stirring is sufficient to make the system uniform, and the higher the temperature, the more rapidly the substitution will proceed. The amount of metal in the finally obtained powder can be adjusted by controlling the substitution rate of metal ions.

The reduction treatment is preferably performed in a reducing gas atmosphere containing 10 moles or more of hydrogen. For this gas atmosphere, hydrogen alone (100 mol %) may be used, or hydrogen and an inert gas such as nitrogen or argon may be used in combination. If the hydrogen concentration is too low, reduction will not proceed sufficiently1
°Reduction is carried out at 150-1000°C, preferably 200-70°C.
If the temperature is too low, the reduction will not proceed sufficiently, and if the temperature is too high, the reduction effect will reach saturation.
