Blue tungsten oxide (BTO) is also called tungsten blue oxide (TBO). Tungsten blue oxide is one of the most important, highly pure intermediates for the production of other tungsten compounds including tungsten metal powder.
Tungsten blue oxides are finely divided blue-violet powders.They are produced by heating ammonium paratungstate at closely controlled temperatures in a reducing atmosphere. GTP produces two standard grades differing mainly in oxygen content. Tungsten blue oxide is used primarily for the production of tungsten metal powder and fine tungsten carbide as well as wire products.
