Tungsten crucible is one of the metal tungsten products, mainly divided into sintering molding (applied to powder metallurgy technology), stamping molding, spinning type. It is formed by turning of tungsten rods (generally the size is relatively small), a variety of welding forming, using pure tungsten plates, tungsten sheets and pure tungsten rods are processed by the corresponding process.

Tungsten crucible can be used in vacuum inert gas below 2600 degrees. Tungsten has a high melting point, good high temperature strength, anti-wear and corrosion resistance, high thermal conductivity, small thermal expansion coefficient, and good hardenability. Tungsten crucibles are widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries.
