The Property And Application of Tungsten Oxide WO3 Powder

What property does tungsten dioxide have?

Tungsten oxide The chemical formula of WO3 is a powdery light yellow triclinic crystal. The temperature of tungsten oxide is increased above 740degC. This causes the tungsten to turn into orange tetragonal crystalline forms, which then return to its original form upon cooling. Tungsten dioxide powder is stable at air temperatures, with a melting and boiling point above 1750degC.
Tungsten Oxide is not soluble in water, nor in any inorganic acid other than hydrofluoric. In hot concentrated sodium chloride solution, WO3 can be dissolved with ammonia. When the temperature exceeds 650°C, it can be reduced with H2 and by C at 1000-1100°C to get tungsten.

How is tungsten dioxide used?

Tungsten dioxide is used in many ways every day. The tungsten oxide is commonly used to create tungstate. tungsten oxide, which is rich in yellow elements and can be used as a paint or ceramic pigment due to the high concentration of yellow elements.

The production of smart and electrochromic windows has used tungsten oxide. These windows are the glass with the electric switch, the performance of light transmission and the applied voltage. Users can tint their windows by changing how much heat or light is being applied. Use of high-density, inert metals is another option. In the 2008-2009 war between Israel and Gaza Strip, the use of these explosives was more prominent.

Some tungsten oxide can be used to make chemical products like paints, coatings, catalysts in the petroleum industry, etc. Although tungsten dioxide is an intermediary product, it is also used to produce metal powders and tungsten carbide powder. This is used for the production of metal products tungsten.
