Sapphire (molecular formula Al2O3) single crystal is an excellent multifunctional material. It has high temperature resistance, good thermal conductivity, high hardness, infrared transmission and good chemical stability. Widely used in many fields of industry, national defense and scientific research (such as high-temperature infrared windows, etc.). At the same time, it is also a widely-used single crystal substrate material. It is the preferred substrate for the current blue, violet, and white light emitting diode (LED) and blue laser (LD) industries, as well as an important superconducting thin film substrate.
