Tungsten trioxide is mainly used for the production of tungsten powder and tungsten carbide powder by calcination reduction, and then for the production of cemented carbide products, such as the manufacture of cutting tools and molds. At the same time, it can also be used to manufacture pure tungsten products, tungsten bars, tungsten wires, tungsten electrodes; and shielding materials for counterweights and radiation. There is also a small amount of colorant used for yellow ceramics in industrial production. In the shipbuilding industry, tungsten oxide is used as an important anti-corrosion paint and coating material.

Tungsten trioxide is a light yellow triclinic powder crystal. When the temperature is higher than 740 ºC, it transforms into an orange tetragonal crystal, and returns to its original state after cooling. It is stable in air, the melting point is 1473ºC, the boiling point is higher than 1750ºC, and the relative density is 7.16.
Tungsten trioxide is the most stable one among the oxides of tungsten. It is insoluble in water and inorganic acids except hydrofluoric acid. It can be dissolved in hot concentrated solution and water to form soluble tungstate. When the temperature is higher than 650 °C, it can be reduced by H2, and at 1000-1100 °C, it can be reduced by C to obtain tungsten powder.
Tungsten trioxide is used for many purposes in daily life. It is often used in industrial X-ray screen phosphors and fire-resistant fabrics to make tungstate. Due to its rich yellow element, tungsten oxide is also used as a pigment in ceramics and paints.
Tungsten trioxide has been employed in the production of electrochromic windows, smart windows. These windows are electrically switched glass, and the light transmission performance varies with the applied voltage. This allows users to tint their windows through changes in the amount of heat or light. Another use is in high-density inert metal explosives, a notable comparison of the use of these devices in the 2008-2009 conflict between Israel and the Gaza Strip.
Part of tungsten oxide is used in the production of chemical products, such as paints and coatings, catalysts in the petroleum industry, etc.; but tungsten oxide is an intermediate product, and a large amount of tungsten oxide is used in metal tungsten powder and tungsten carbide powder, and then used in the production of metal tungsten products It is widely used in the production of tungsten alloy products, such as tungsten copper, tungsten nickel, tungsten nickel iron, tungsten silver, tungsten rhenium, tungsten thorium, etc., and the most widely used in the contemporary industrial field is tungsten as the base material Production of various grades and uses of cemented carbide products.
