Sapphire is a kind of single crystal of alumina (Al2O3). Optical penetration zone of sapphire is very wide. Sapphire has good light-admitting quality to near ultraviolet (190nm) to the middle infrared. Sapphire crystal has excellent optical properties, mechanical properties and chemical stability, high strength, high hardness and corrosion resistance. So sapphire can work in harsh conditions close to 2000 ℃ high temperature, it is widely applied in the infrared military equipment, satellite technology and high intensity laser window material. Due to its unique structure, excellent mechanical properties and good thermal properties make sapphire crystal becomes the ideal backing material for semiconductor GaN/Al2O3 (LED), large scale integrated circuit and superconducting nanostructured film etc.. In recent years, with the rapid growth of LED TV, LED Monitor, LED NB, LED Phone and LED lighting markets, sapphire market also developed.

Because of high temperature resistance, low pollution characteristics of tungsten and molybdenum, tungsten and molybdenum can be widely used  as components for sapphire crystal growth furnace, including tungsten crucible / molybdenum crucible, heater, tungsten tube, heat insulation screen, crucible cover etc..
