Optical ceramics are advanced ceramics which are optically transparent. They are the transparent polycrystalline materials which can be used in place of single crystals. In order to make ceramic transparent, there is a need to eliminate the inner pore and impurity along with the birefringence effect. Optical ceramics possess various properties, such as high thermal resistance, strength, hardness, and scratch resistance; and are also, electrically resistant.
