Description

Aluminum Oxide Sapphire Crystal Substrates Description

Aluminum oxide sapphire crystal substrates have good thermal characteristics, excellent electrical and dielectric properties, and are resistant to chemical corrosion. Al2O3 sapphire crystal substrates are also resistant to high temperatures, good thermal conductivity, high hardness, infrared transmission, and chemical stability. They are widely used in high temperature resistant infrared window materials, III-V nitrides and various epitaxial film substrate materials.
