Tungsten crucible.Tungsten crucible is one of the metal Tungsten products, mainly divided into sintering molding (used in powder metallurgy technology), stamping molding, spinning type. Use tungsten rods turning processing molding (generally the relatively small size), welding forming a variety of, is made of pure tungsten plate, tungsten and pure tungsten rod through the corresponding process. Tungsten crucible can be used in the vacuum of inert gas under 2600 degrees. Tungsten the melting point of high boiling point, good high temperature strength, wear-resistant corrosion resistance, thermal conductivity, thermal expansion coefficient is small, good harden ability. Tungsten crucible is widely used in rare earth smelting, quartz glass, electronic spray, crystal growth, etc.
