Sapphire Dan Changjing Tungsten Crucible Furnace

First, Sapphire tungsten crucible furnace Dan Changjing About Sapphire Dan Changjing tungsten crucible furnace

Sapphire Dan Changjing tungsten crucible furnace is one of tungsten products, mainly divided sintering ( applied to the powder metallurgy technique ) , stamping , spinning type . Turning the use of tungsten rod shape ( generally relatively small size ) , forming a variety of welding , the use of pure tungsten plate , tungsten film processing and pure tungsten rod made ​​by the corresponding process . Sapphire Dan Changjing tungsten crucible furnace using an inert gas in a vacuum degrees in 2600 . The melting point of the high boiling point of tungsten , high temperature strength , wear resistant , high thermal conductivity , low coefficient of thermal expansion , good hardenability . Widely used in the tungsten crucible smelting of rare earth , quartz glass, electronic spraying, and other crystal growth sectors .

Tungsten melting point, high boiling point , high temperature strength , anti-friction , corrosion resistance, high thermal conductivity , low coefficient of thermal expansion , good hardenability , thanks to such excellent properties, are widely used in a tungsten crucible smelting of rare earth , quartz glass, electronic spraying , crystal growth and other industries.

Second, Sapphire Dan Changjing tungsten crucible furnace physical and chemical properties

1 Purity : W ≥ 99.95%;

2 , Density : ≥ 18.5g/cm3;
 
3, The maximum application temperatures : 2400 ℃.

Third, Sapphire Dan Changjing tungsten crucible furnace uses

Since the melting point of tungsten 3410 ℃, and therefore is widely used in the tungsten crucible core container sapphire single crystal growth furnace , quartz glass melting furnace, the rare earth and other industrial furnace, smelting furnace , the use of working temperatures generally above 2000 ℃. Especially for sapphire single crystal growth furnace , the high purity , high density, without internal cracks, precise size , smooth inner and outer walls , and other features of the tungsten crucible for sapphire crystal growth process seed success rate , pulling quality control, from crystal stick pan and life has played a key role.
