Multilayer sintered ceramic body
Disclosed herein is a multilayer sintered ceramic body comprising: at least one first layer comprising polycrystalline YAG, where the at least one first layer comprising polycrystalline YAG comprises pores, where the pores have a maximum size of 0.1 [mu] m to 5 [mu] m; at least one second layer comprising alumina and zirconia, wherein the zirconia comprises at least one of stabilized zirconia and partially stabilized zirconia; and at least one third layer comprising at least one of YAG, aluminum oxide, and zirconium oxide wherein the absolute value of the difference in coefficient of thermal expansion (CTE) between the at least one first layer, the at least one second layer, and the at least one third layer is 0 to 0.75 x 10-6/DEG C, as measured according to ASTM E228-17, and the absolute value of the difference in coefficient of thermal expansion (CTE) between the at least one first layer, the at least one second layer, and the at least one third layer is 0 to 0.75 x 10-6/DEG C, wherein the at least one first layer, the at least one second layer and the at least one third layer form a monolithic multilayer sintered ceramic body. The invention also discloses a preparation method.
本文公开了一种多层烧结陶瓷体，该多层烧结陶瓷体包含：包含多晶YAG的至少一个第一层，其中包含多晶YAG的该至少一个第一层包含孔隙，其中所述孔隙具有0.1μm至5μm的最大尺寸；包含氧化铝和氧化锆的至少一个第二层，其中该氧化锆包含稳定的氧化锆和部分稳定的氧化锆中的至少一者；以及包含YAG、氧化铝和氧化锆中的至少一者的至少一个第三层，其中如根据ASTM E228‑17测量的，该至少一个第一层、该至少一个第二层和该至少一个第三层之间的热膨胀系数(CTE)差的绝对值为0至0.75×10‑6/℃，其中该至少一个第一层、该至少一个第二层和该至少一个第三层形成整体多层烧结陶瓷体。还公开了制备方法。
