Sapphire (molecular formula Al2O3) single crystal is an excellent multifunctional material. It is resistant to high temperature, good thermal conductivity, high hardness, infrared transmission and good chemical stability. It is widely used in many fields of industry, national defense and scientific research (such as high temperature resistant infrared windows, etc.). It is also a widely used single crystal substrate material and is the preferred substrate for the current blue, violet and white light emitting diode (LED) and blue laser (LD) industries (need to first epitaxy GaN film on sapphire substrate), as well as an important superconducting thin film substrate. In addition to Y-series, La-series and other high-temperature superconducting films, it can also be used to grow new practical MgB2 (magnesium diboride) superconducting films (usually single-crystal substrates are subject to chemical corrosion during the production of MgB2 films).
For sapphire product, we have sapphire window, sapphire lens, sapphire bearing, sapphire rod, sapphire prism etc.
