Tungsten trioxide is mainly used for calcination reduction to produce tungsten powder and tungsten carbide powder, which is then used in the production of cemented carbide products such as tools and molds. 

Tungsten trioxide can also be used to make pure tungsten products, tungsten rods, tungsten wires, tungsten electrodes, and shielding materials for counterweights and radiation. There is also a small amount of colorant used as a yellow ceramic in industrial production. In the marine industry, tungsten oxide is used as an important anticorrosive paint and coating material.
