Tungsten oxide is also called tungsten trioxide, including yellow tungsten oxide (YTO, WO3) and blue tungsten oxide (BTO, WO2.9). The oxygen for blue tungsten oxide is 2.90-2.97.

Typical application: Tungsten Trioxide powder is mainly used for producing tungsten powder and tungsten carbide powder. YTO-The yellow color makes it widely used as coloring agent in ceramic and paint. BTO is gradually becoming the main raw material to prepare special tungsten powder and other products.
