Multilayer sintered ceramic body and preparation method
A multilayer sintered ceramic body is disclosed, the multilayer sintered ceramic body comprising: at least one first layer comprising at least one YAG crystalline phase, where the at least one first layer has at least one surface; and at least one second layer comprising aluminum oxide and at least one of stabilized zirconium oxide and partially stabilized zirconium oxide wherein the at least one surface of the at least one first layer comprises pores wherein the pores have a maximum size of 0.1 [mu] m to 5 [mu] m as measured by SEM, and wherein each of the at least one first layer and the at least one second layer has a coefficient of thermal expansion (CTE) wherein the CTE of the at least one first layer and the CTE of the at least one second layer differ from 0 to 0.6 x 10-6/DEG C as measured according to ASTM E228-17. The invention also discloses a preparation method.
本发明公开了一种多层烧结陶瓷体，所述多层烧结陶瓷体包括：至少一个第一层，所述至少一个第一层包含至少一个YAG晶相，其中所述至少一个第一层具有至少一个表面；和至少一个第二层，所述至少一个第二层包含氧化铝以及稳定的氧化锆和部分稳定的氧化锆中的至少一种，其中所述至少一个第一层的所述至少一个表面包含孔隙，其中如通过SEM测量的，所述孔隙具有0.1μm至5μm的最大尺寸，并且其中所述至少一个第一层和所述至少一个第二层中的每一者具有热膨胀系数(CTE)，其中如根据ASTM E228‑17测量的，所述至少一个第一层的CTE和所述至少一个第二层的CTE相差0至0.6×10‑6/℃。还公开了制备方法。
