High-quality sapphire material has a series of characteristics such as high strength, high hardness, high temperature resistance, abrasion resistance,corrosion resistance, good light transmission performance (in the 170nm ~ 6000 nm), excellent electrical insulation performance, and good mechanical properties.' The chemical performance is very stable, free from acid and alkali corrosion. The hardness of sapphire is high, with Mohs hardness level 9, second only to diamond (level 10). The infrared transmittance hardly changes with temperature. Therefore, optical components and infrared-transmitting optical windows made of high-quality synthetic sapphire are used in military night vision aiming far-infrared equipment, low-temperature laboratory observation windows, and high-precision navigating, aerospace and aviation instrumentation, such as in laser windows, mirrors, semiconductor epitaxial substrates,insulated substrate integrated chips, military night vision infrared transmission equipment, semiconductor epitaxial substrates, LED epitaxial wafers, SOS technology substrates, integrated circuits, logic components, microcomputers, aerospace and space technology sensors, pressure sensors, acceleration sensors, ion-sensitive, bio-sensitive sensors, high-speed integrated circuit substrates, integrated optical circuit substrates, ultra-high filters, delay circuits, etc.. Rectangular windows are also used in beauty industry.
