2", 4" Sapphire Substrate

Quantity:

Product introduction: Sapphire wafer is a kind of single crystal with hexagonal structure manufactured by AlO3 of high purity. It has the advantages of corrosion resistance, high temperature and pressure resistance, low dielectric loss and high heat stability. It is the ideal material for Light Emitting Diode and lasing diode.

Application: PSS substrate, epitaxial substrate.
