Surface: grounded, ungrounded
Appearance:silver grey metal luster
Advantages of tungsten crucible: low thermal expansion; high density;erosion resistance;high strength and low resistivity
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.
