CERAMIC WITH EXCELLENT THERMAL SHOCK RESISTANCE
Disclosed is a ceramic having excellent thermal shock resistance, which can suppress cracks due to external thermal shock by fibrous zirconia dispersed in a random direction. The ceramic of the present invention is represented by chemical formula 1, (A_xB_(1-x))_2Zr_2O_7, wherein A is a lanthanum-based rare earth metal, B includes at least one of yttria and a lanthanum-based rare earth metal which is not included in A, and 0 < x <= 1 is satisfied. The ceramic represented by the chemical formula 1 is a porous ceramic, has pores and fibrous zirconia dispersed in a random direction, and suppresses cracks by external thermal shock by the fibrous zirconia.
본 발명은 랜덤 방향으로 분산되어 있는 섬유상의 지르코니아에 의해 외부 열충격에 의한 균열을 억제할 수 있는 내열충격성이 우수한 세라믹에 대하여 개시한다. 본 발명에 따른 세라믹은 하기 화학식 1로 표시되고, [화학식 1] (AB)ZrO상기 A는 란탄계 희토류 금속이고, 상기 B는 이트리아 및 상기 A에 포함되지 않은 란탄계 희토류 금속 중 1종 이상을 포함하고, 상기 x는 0
