Effect of powder treatment on optical quality of transparent ceramics
, 2021 Yttrium aluminum garnet (Y3Al5O12) has an isotropic crystal structure that makes it transparent to visible and IR electromagnetic radiation even in polycrystalline ceramic form. Only fully dense and defect-free materials can be transparent.
