Features:
Sapphire (also known as sapphire, molecular formula for Al2O3) single crystal is an excellent multifunctional material. It has high temperature resistance, good heat conduction, high hardness, infrared transmission and good chemical stability. It is widely used in many fields of industry, national defense and scientific research (such as high temperature infrared window). At the same time, it is also a kind of widely used single crystal substrate material. It is the first choice substrate in the current blue, violet, white light-emitting diode (LED) and blue laser (LD) industry (gallium nitride film needs to be epitaxial on the sapphire substrate first), and it is also an important superconducting film substrate. In addition to the Y-system, La system and other high-temperature superconducting films, it can also be used to grow new practical MgB2 (magnesium diboride) superconducting films (usually the single-crystal substrate will be chemically corroded during the fabrication of MgB2 films). High quality artificial sapphire crystal materials have good light transmittance in the 0.20 ~ 5.50 渭 M band, the infrared transmittance almost does not change with the temperature, and the transmittance to ultraviolet and visible light is also very high, so it is commonly used to replace other optical materials to make optical components and infrared optical windows, and is widely used in infrared and far-infrared military equipment, such as: night The optical infrared and far-infrared collimators, night vision cameras and other instruments, as well as the instruments and meters of satellites and space technology, as well as the windows used as high-power lasers, various optical prisms, optical windows, UV and IR windows and the observation ports of lenses and low-temperature experiments, are fully used in the high-precision instruments and meters for navigation, aerospace and aviation.
