High Resistance Sapphire Polished Wafer 3 Inch C-Plane Optical Crystal
Sapphire is a single crystal of alumina and is the second-hardest material in nature, after diamond. Sapphire has good light transmittance, high strength, collision resistance, wear resistance, corrosion resistance and high temperature and high pressure resistance, biocompatibility, is an ideal substrate material for the production of semiconductor optoelectronic devices, the electrical properties of sapphire make it become the substrate material for the production of white and blue LED.
