Violet tungsten oxide (VTO) is a kind of tungsten oxide. Violet tungsten oxide is a finely divided violet crystalline powder. It is produced by rotary calcining ammonium paratungstate at closely controlled temperatures in a reducing atmosphere. Violet tungsten oxide is used primarily for the production of tungsten metal powder and tungsten carbide.
