Description

SS-LA500 is high purity alumina powder which produced by international advanced alkoxide hydrolysis method. high purity 99.99% .Perfect performance in improving ceramic density, smoothness, the fracture toughness, creep resistance and wear resistance as well as keep temperature balance. It also be used in chemical fiber products and high pressure sodium as far-infrared emission and insulation material because of its excellent far-infrared emission ability.

In addition, alpha alumina has high resistivity and good insulation performance, it can be applied to YGA laser crystal and integrated circuit substrate as main fittings.
