Tungsten Crucible Chemical Properties

Tungsten crucible is one of metal tungsten products, mainly divided into sintering molding (applied to powder metallurgy technology), stamping molding, spinning type. The use of tungsten rod turning processing molding (generally smaller size), welding molding a variety of, using [2] pure tungsten plate, tungsten sheet and pure tungsten rod by the corresponding process. Tungsten crucible can be used in vacuum inert gas below 2600 degrees. Tungsten has high melting and boiling points, good high temperature strength, wear and corrosion resistance, large thermal conductivity, small coefficient of thermal expansion and good hardenability. Tungsten crucible is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries.
