Al2O3 Sapphire Crystal Wafer Industrial Defense Security Scientific Research
Industrial defense security scientific research Al2O3 Sapphire Crystal wafer
Al2O3 crystals or Sapphire is a multi-function crystal materials with excellent properties: good thermos-stability, high thermal conductivity, high hardness, high transmission at infrared wavelength rang and excellent chemical stability. Sapphire is widely used in industrial, defense and security and scientific research fields. sapphire is also an important substrate materials for high temperature superconductivity applications, it can be used for film growth of Y-series, La-series, and it is also used to grow the superconductivity film of MgB2.
