Tungsten trioxide is mainly used in calcining and reducing to produce tungsten powder and tungsten carbide powder, and then used in the production of cemented carbide products, such as tools and molds. It can also be used to manufacture pure tungsten products, tungsten bars, tungsten wires and tungsten electrodes. And the use of counterweight and radiation shielding materials. A small amount is also used in industrial production as a colorant for yellow ceramics. In the shipbuilding industry, tungsten oxide is used as an important anticorrosive paint and coating material.
