Properties
Sapphire is the hardest of all known oxide crystals with a 9 on the Mohs scale. It is second in hardness only to diamond, and retains its high strength at high temperatures. Sapphire crystals have good thermal properties, with excellent electrical and dielectric properties. In addition, Sapphire combines zero porosity with near total resistance to acids and alkaline substances. Sapphire is insoluble in watch, and only reacts with hydrofluoric acid, phosphoric acid and potassium hydroxide at high temperature of above 300 degree celsius.
Shanghai Optics has been a provider of sapphire wafers, sapphire lenses, sapphire substrates, watch glasses, and sapphire boule for many years. Sapphire is anisotropic hexagonal crystal. Its properties depend on crystallographic direction (relative to the optical C-axis). Our sapphire wafers are generated using the latest technology to maximize quality and transmittance. Because of our product’s quality, you can trust that it is your best choice for a variety of demanding applications.
