Sapphire (Sapphire, also known as the white stones, formula Al2O3) crystal is an excellent multi-purpose material. It is high temperature, thermal conductivity, high hardness, through infrared, good chemical stability. Widely used in many fields of industrial, defense and scientific research (such as high-temperature infrared window, etc.). It is also an extensive use of the single crystal substrate material, is the current blue, purple, white light emitting diode (LED) and a blue laser (LD) Preferred substrates industry (need to hold on a sapphire substrate epitaxial gallium nitride thin film) is important superconducting film substrate. In addition to the production line Y-, La- Department and other high-temperature superconducting thin films can also be used outside the growth of new practical MgB2 (magnesium diboride) superconducting thin films. My company has choline hydrolysis using proprietary technology, through strict control of raw materials and production process, alumina obtained has 5N purity alumina has a high density advantages, mainly for Kyropoulos, guided touch method, TGT, Czochralski method, such as the preparation of large-size sapphire crystal.
