Co to jest Ceramic Transparent?

To fuly meticate thee mechanical performance of transparent ceramics, one mutt first understand thee optical contribute they overcome. Traditional ceramics are typically opaque because light is scattered by internal pores, second-faxe inclusions, and birefringence at grain boundaries.
