Product Description
Why Choose sapphire crystal?
Sapphire (Al2O3) is a superior optical material which is used for its excellent optical, chemical and physical properties for use in the UV, Visible and Infra-red regions. Sapphire crystal is extremely hard and scratch resistant. It is the hardest of the oxide crystals, being the next strongest material to diamond. Sapphire is able to be cut thinner than alternative crystals due to its structural durability.
Sapphire is grown using a variety of methods. Standard grade Sapphire material is grown by Verneuil and Czochralski methods, whereas higher quality Sapphire is manufactured by the Kyropulus growth method.
