Al2O3 Single Crystal Description

Al2O3 crystal 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.
