LED Grade 6 Inch Sapphire Crystal Lenses Crystalline Structure

6”Sapphire Wafer, 6inch Sapphire Substrate

All wafers are produced from low stress high purity, LED grade HEM grown sapphire with a uniform crystalline structure, free of subgrains, bubbles and inclusions. This results in superior performance in downstream MOCVD processing with thin films and increased yields.

What is sapphire?

Synthetic Sapphire is a single crystal form of corundum, Al₂O₃, also known as alpha-alumina, and single crystal Al₂O_{3,have 9.0 hardness.}

Sapphire is aluminium oxide in the purest form with no porosity or grain boundaries, making it theoretically dense.

The combination of favourable chemical, electrical, mechanical,optical, surface, thermal, and durability properties make sapphire a preferred material for high performance system and component designs. For various semiconductor applications,

sapphire is the best choice in comparison with other synthetic single-crystals.
