Sapphire is a single crystal of alumina and is the second hardest material in nature, after diamond. Sapphire has good light transmittance, high strength, collision resistance, wear resistance, corrosion resistance and resistance to high temperature and high pressure, biocompatibility, can be made into various shapes of objects. It is an ideal substrate material for making semiconductor optoelectronic devices.
Application: Sapphire single crystal is an excellent multifunctional material. Can be widely used in industry, national defense and scientific research and other fields (such as high temperature resistant infrared window). It is also a widely used single crystal substrate material. Is the current blue, purple, white light emitting diode (LED) and blue laser (LD) industry of the first choice substrate (need to epitaxy gallium nitride film layer on sapphire substrate), is also an important superconducting thin film substrate. In addition to making Y- series, La- series and other high temperature superconducting thin films, it can also be used to grow new practical MgB2 (magnesium diboride) superconducting thin films.
