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.
