PROBLEM TO BE SOLVED: To provide a ceramic conjugate available for long term in an environment exposed to high temperature repeatedly.SOLUTION: In a ceramic conjugate 10, a first ceramic sintered compact 1 and a second ceramic sintered compact 2 are joined through a conjugation layer 3 consisting of oxide containing rare earth elements, silicon, aluminum and magnesium. The oxide converted content of the rare earth elements in outside 3a of the conjugation layer 3 is more than the oxide converted content of the rare earth elements in inside 3b of the conjugation layer 3.SELECTED DRAWING: Figure 1
【課題】高温に繰り返し曝される環境においても長期間に亘って使用可能なセラミック接合体の提供。【解決手段】第１のセラミック焼結体１と第２のセラミック焼結体２とが、希土類元素、珪素、アルミニウムおよびマグネシウムを含む酸化物からなる接合層３を介して接合されてなり、接合層３の内部３ｂにおける希土類元素を酸化物換算した含有量より、接合層３の外部３ａにおける希土類元素を酸化物換算した含有量が多いセラミック接合体10。【選択図】図１
