Tungsten crucible is one of tungsten products, it is mainly divided into sintering crucible, stamping crucible and spinning crucible. It uses the molybdenum rod to machining mold and welding mold. It is made of pure tungsten plate, tungsten sheet and pure tungsten rod by processing. It can be used in vacuum and inert gas below 2600 degrees.

Tungsten has high melting point, high boiling point, good high temperature strength, high heat conduction rate, low coefficient of thermal expansion and good quenching, which is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth industry.

The main application of tungsten crucible: it is mainly used for rare earth metal smelting, heating element of induction furnace, quartz glass melting, high temperature vessels. It is made of FW-1 materials in tungsten powder.
