Sapphire Dan Changjing Furnace Hot Zone

Sapphire Dan Changjing Furnace Hot Zone

Sapphire (Sapphire) is an aluminum oxide (Al2O3) single crystal, the optical penetration with a very wide, from near-ultraviolet light (190nm) to have a mid-infrared

Sapphire has good light transmittance. Sapphire crystal has excellent optical properties, mechanical properties and chemical stability, high strength, hardness, corrosion resistance, high temperature 2000 ℃ in proximity to work under harsh conditions, they have been widely used in military infrared devices, satellite space technology, high-intensity laser window material. Its unique lattice structure, excellent mechanical properties, good thermal properties make sapphire crystal as the practical application of semiconductor GaN/Al2O3 light-emitting diode (LED), LSI SOI and SOS and nanostructured superconducting films such as the most ideal substrate material. With the recent LED TV, LED Monitor, LED NB, LED Phone and LED lighting market continues rapid growth, a strong impetus for the production of LED sapphire substrate market demand expansion.

Benefits：

The production technology is mature sapphire substrate, the device of good quality
Sapphire good stability, can be used in high-temperature growth process
Sapphire has high mechanical strength, ease of handling and cleaning

Common Crystal Growth Method:
