Sapphire wafer

Sapphire crystal is a material of a unique combination of physical, chemical and optical properties, which make it resistant to high temperature, thermal shock, water and sand erosion, and scratching. Sapphire wafers is widely used in semiconductor (MOCVD epitaxial GaN substrate),lasers, infrared, electronics, measuring instruments, military, aerospace and others high-tech industry.
