Sapphire material has a series of characteristics such as high strength and hardness, high temperature resistance, friction resistance, corrosion resistance, excellent light transmittance, and electrical insulation performance. High strength sapphire glass mirror is a mirror surface synthesized by artificial compression, which has the advantages of high density and less susceptibility to scratches. Therefore, as an important technical crystal material, sapphire chips have been widely used in fields such as laser windows and mirrors, semiconductor silicon epitaxial substrates, integrated chips with insulating substrates, industrial infrared transparent materials, and semiconductor gallium nitride epitaxy.
