tungsten crucible , wolfram crucible can be processed in sintered , forged and lathed . Surface: grounded, ungrounded; Advantages of tungsten crucible: low thermal expansion; high density;erosion resistance;high strength and low resistivity; it commonly used for sapphire single crystal growth furnace;
Tungsten Crucible
Mainly divided into sintering molding (applied to powder metallurgy technology), stamping molding, spinning type. It is formed by turning the tungsten rod (the general size is relatively small), and the welding is various. The pure tungsten plate, the tungsten piece and the pure tungsten rod are processed by corresponding processes. Tungsten rhenium can be used in vacuum inert gases below 2600 degrees. Tungsten has a high melting point, high temperature strength, anti-wear and corrosion resistance, high thermal conductivity, small thermal expansion coefficient and good hardenability. Tungsten-rhenium is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries
