What Is A Sapphire?

Sapphire (Sapphire) is an alumina (Al2O3) single crystal , the optical penetration with a wide range from the near UV (190nm) to the infrared lens has good optical properties of single crystal alumina . Sapphire crystal has excellent optical properties, mechanical properties and chemical stability , high strength , hardness , corrosion resistance, can work in temperatures close to 2000 ℃ harsh conditions , they have been widely used in military infrared devices , satellite space technology, high-intensity laser window materials . Its unique lattice structure , excellent mechanical properties , good thermal properties make sapphire crystal semiconductor GaN/Al2O3 become practical light-emitting diode (LED), LSI SOI and SOS nanostructured superconducting films and the most ideal substrate material . With the recent LED TV, LED Monitor, LED NB, sustained high growth LED Phone and LED lighting market , driven by strong demand for the production of LED sapphire substrate market expansion.

Since tungsten and molybdenum has a high temperature , low pollution and other characteristics, are widely used to make Sapphire Dan Changjing furnace hot zone components, including tungsten crucible / molybdenum crucible , heating element , tungsten tube, heat shield, support base, the seed rod , the crucible cover. Heating element cage structure using tungsten or tungsten mesh heating element heating element , help provide a uniform and stable temperature field .
