Tungsten Crucible for Sapphire Growth Furnace

Tungsten crucible and related tungsten thermal system for sapphire growth furnace owns the properties of high density, high purity and high processing accuracy. Tungsten crucible for sapphire growth furnace is made of the material of pure tungsten, whose purity is over 99.95%, and the density is about 18.2g/cm3.
The manufacturing techniques of tungsten crucible for sapphire growth furnace are sintering, metal forming, spinning type, the use of molybdenum rod turning molding, or welding of a variety of pure tungsten plates, tungsten plates and pure tungsten rod. The tungsten crucible can be used under the high temperature of 2600 degree.

Tungsten crucible is also used in sapphire growth furnace is mainly because of the properties of tungsten, which are high boiling point, high melting point, thigh temperature resistance, high corrosion resistance,low thermal expansion coeffient, and high thermal conductivity. Besides tungsten crucible for sapphire growth furnace, tungsten crucible is also used in metallurgy of rare earth, ion plating and quartz glass.

It is because of the properties of tungsten crucible that tungsten crucible is chose as one important part in the process of growing sapphire crystal. Under high temperature, tungsten crucible will not react with Al2O3, so that the purity of sapphire crystal can be assured.
