らに優れた。Effects of Examples In Examples 1 to 5, Mn reacts with the grain boundary components of the ceramic body to improve the bonding properties with the ceramic body, and Mo, which does not sufficiently penetrate inside the ceramic body and has a high melting point,
Since they have an intermediate layer made of W, they are both superior in strength and airtightness compared to the comparative example. In particular, in Example 1 (using Mo), the bonding strength was even better than in Example 3 (■').

。Furthermore, the greater the blending ratio of M g A + 204, the better the bonding strength. That is, it shows a large value in the order of Example 4, Example [11, and Example 5], and on the other hand, it shows a large value of 80%.
(Example 5) also had superior strength and airtightness compared to the conventional one.

ある。Furthermore, M g A I z O+ is 1 for spinel.
As shown above, compared to alumina, the swelling phenomenon is drastically reduced to about 1/9 or less, and it has excellent radiation resistance.
This can prevent the occurrence of cracks in the ceramic body. Therefore, as in Examples 1 to 5 above, MgA1201
It is clear that radiation resistance is significantly superior to that of alumina even when the mixing ratio is 80%, 90%, or 95%.

密性に優れる。[Effect of heating] As mentioned above, the bonded body of the ceramic body and metal body of the present invention mainly has grains such as Mn that react with the grain boundary constituent components of the ceramic body and penetrate into the surface of the ceramic body. field reactive metal,
If this penetration is insufficient, the ceramic body will have an intermediate layer containing a high melting point metal that forms a metallized surface that is advantageous for bonding to a metal body and has excellent heat resistance and bonding strength. Therefore, the present invention is excellent in joint strength and airtightness of the joint.
