Tungsten Crucible

  • Tungsten Crucible
  • Sintered Tungsten Crucible
  • Tungsten Crucibles

Tungsten crucible is one of the tungsten products. It can be processed by sintering, stamping and rotatable machining. Sintered product is manufactured by powder metallurgy technology. The most common application of sintered products is the crucible in the melting furnaces. Tungsten crucibles can be manufactured from pure tungsten plates or rods through machine shaping and welding processes. Tungsten crucible is widely applied in sapphire production, also used in quartz glass melting furnace, rare earth smelting furnace and other furnaces as the core container. The melting point of tungsten is 3410 ℃. The production process of tungsten crucible is: tungsten powder-sieving-furnace apart-isostatic pressing-lathe machining-medium frequency sintering-second lathe machining-packing.


Sintered Tungsten Crucible

Sintered tungsten crucible is widely used in many fields because of its corrosion resistance in molten metals and metal oxides. It can be used to grow single crystals from fused corundum. It is also used in electronics as heat evaporation and deposition vessels for various substances.

Tungsten Crucible for Vacuum Coating

According to different production methods, tungsten crucibles used for vacuum coating are mainly divided into sintering forming, stamping forming, spinning forming, turning forming and welding forming. Among them, turning forming is the most important. We suggest that the working temperature of the vacuum coated tungsten crucible should be controlled below 2600 ℃. In the field of optical glasses, the vacuum coating crucible is mainly used for heating elements of containers and vacuum coating machines. It also has high thermal conductivity, thermal expansion coefficient and good hardness.
