CERAMIC CONJUGATE

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.
