Tungsten Crucible

Purity: 99.95%

Surface: grounded, ungrounded

Appearance:silver grey metal luster

Advantages of tungsten crucible: low thermal expansion; high density;erosion resistance;high strength and low resistivity

Tungsten Crucible Applications

Since the temperature in working environment of tungsten crucible is above 2000℃, it commonly used for sapphire single crystal growth furnace

Applied for quartz glass melting furnace

Used for rare earth smelting furnace

Used for sintering metal mold of high melting point

Tungsten crucibles are also widely used in other industries like ceramics and metallurgical industries, machinery processing and light industries.
