Chemical Products

Chemical Products clipFor the manufacture of chemical products, commercially available tungsten compounds such as sodium tungstate, ammonium tungstates, tungsten oxides or tungstic acid are commonly used as raw materials. The following list gives a few examples.

  • Inorganic pigments for ceramic glazes and enamels:
    • Tungstic acid or tungsten oxide is used for bright yellow glazes.
    • Tungsten bronzes, i.e. partly reduced alkali and alkaline earth tungstates, are available in many bright colours.
  • Barium and zinc tungstate are examples for bright white pigments.
    Coloured organic dyes and pigments based on phospho tungstic acid and phospho tungsto-molybdic acid are made for paints, printing inks, plastic, rubber and other materials.
  • Tungsten disulphide is a lubricant for temperatures above the application range of molybdenum disulphide. It has also been used to form a self-lubricating surface on razor blades.
  • Organic tungsten compounds have been patented as viscosity stabilisers in lubricant oils.
