Sapphire application:
Good performance, become the most widely used oxide substrate material, mainly used as semiconductor film substrate material, large-scale integrated circuit substrate and so on.
Sapphire crystal is also an excellent window for infrared military devices, missiles, submarines, satellite space technology, detection and high-power Laser (Laser), excellent optical materials, wear-resistant bearing materials, especially in missile fairing, submarine Windows and atomic clocks and other military supplies irreplaceable role.
In other civilian aspects, sapphire can also be used as transparent electronic materials, lamps and Windows, semiconductor crystals, circular bearing devices, thermal insulators, thermocouples, ultraviolet infrared optical Windows and gravity wave detection instruments.
Optical window and fairing
The infrared optical window and fairing with excellent comprehensive performance are the key components in the high-speed aircraft system. The materials must have high transmittance, low scattering, high strength, low elastic modulus, high melting point, high thermal conductivity, high thermal shock quality factor, geothermal radiation, and resistance to the erosion and corrosion of jet, fuel, hail, rain, seawater, salt spray and sand in the use band. A series of excellent comprehensive properties such as strong light irradiation resistance.
Although diamond has ideal optical, mechanical and thermal properties, there are still some technical bottlenecks from the practical application of diamond as an independent infrared and optical window and fairing.
Magnesium fluoride has good optical properties and mature infrared optical window made of blue Doctor single crystal, but its mechanical strength is very low.
Although alumina nitride has higher mechanical strength, its cutoff wavelength is shorter, but its transmittance changes obviously with the change of temperature.
Although spinel has high melting point and good chemical stability, its compressive strength is not high.
