Multilayer sintered ceramic body and preparation method thereof
Disclosed is a multilayer sintered ceramic body comprising: at least one first layer (100) comprising polycrystalline YAG wherein the at least one first layer (100) has at least one surface; and at least one second layer (102) comprising magnesium aluminate spinel wherein at least one surface of the at least one first layer (100) comprises pores wherein the pores have a maximum dimension of 0.1 pm to 5 pm as measured using SEM, and wherein each of the at least one first layer (100) and the at least one second layer (102) has a coefficient of thermal expansion (GTE), wherein the GTE of the at least one first layer and the GTE of the at least one second layer differ from 0 to 0.6 x 10-6/DEG C. The invention also discloses a preparation method.
