What is sapphire?
Sapphire, the single crystal form of alumina (Al2O3), synthetic sapphire is often the material of choice for design engineers dealing with extreme conditions of high temperature, high pressure and harsh chemical environments.Now synthetic sapphire products are widely used in mobile devices windows, LED substrates, watch lenses, customized sapphire components and military applications.
