what is sapphire(Al2O3)?

Al2O3 single crystal, also called sapphire, is used for blue LED substrate optical window. MTI grows high quality Sapphire via CZ method and produces sapphire substrate from 10x10 mm to 100 mm diameter for the most competitive price.

Sapphire (single crystal of Al2O3) is being used extensively as a substrate for III-V nitrides and for many other epitaxial films.

application of synthetic sapphire

synthetic sapphire often used as infrared filters in military and industrial applications watch glasses, watch crystals, and gauge Silicon on sapphire wafers; Superconductor substrate, high temperature and pressure windows, electrical insulators, thin film deposition, transparent electronic substrate.

we supplies precision optical components in various materials and configurations.Sapphire’s hardness and ability to accept a high polish make it an ideal bearing component.Synthetic Sapphire is widely used in medical applications for its transmission, high thermal conductivity and ability to autoclave.Sapphire’s hardness and ability to transmit from UV to IR make it ideal for demanding applications in Space and Airplane systems.
