The ammonium paratungstate (APT) is the most important starting material in the tungsten industry, where usually its most stable APTÂ4H2O form is used. Tungsten compounds such as, tungsten oxides, tungsten carbides or tungsten metal can be prepared with APT. All these tungsten products have important applications in a many fields. Among which, tungsten oxides are widely used in catalysts, gas sensors, and photocatalysts. Tungsten carbide products have been used as catalysts as well, but another important application field they shared is being the hard component in cutting and drilling tools.
