Tungsten trioxide is an inorganic compound with the chemical formula WO3. It is a yellow powder that is insoluble in water, but soluble in alkalis and slightly soluble in acids. It is used in the production of high-melting alloys and hard alloys, tungsten filaments, and fireproof materials. It can be obtained by melting tungsten ore with soda ash and adding acid. Tungsten trioxide is mainly used for calcination and reduction to produce tungsten powder and tungsten carbide powder, which are then used in the production of hard alloy products, such as cutting tools and molds. It can also be used to manufacture pure tungsten products, tungsten bars, tungsten filaments, tungsten electrodes; and for use as a weighting and radiation shielding material. In industrial production, it is also used as a coloring agent for yellow ceramicware in small quantities. In the shipbuilding industry, tungsten trioxide is used as an important anti-corrosion paint and coating material.
