What is Tungstentrioxide?
Tungsten Trioxide is a powdery triclinic crystal in a light yellow color. If the temperature rises above 740degC it becomes orange tetragonal prisms that return to its original state upon cooling. It is stable when in air with a melting and boiling point above 1750degC.
Tungsten trioxide, the most stable type of tungsten dioxide, is a solid. It is insoluble with water and other inorganic acid except hydrofluoric. It can be dissolved into a hot, concentrated sodium hydroxide mixture and ammonia in order to create soluble tungstate. It can be oxidized by H2 at temperatures above 650 and reduced by C for tungsten powder between 10001100.
Tungsten Trioxide Application:

Tungsten Trioxide is widely used in the daily life. The tungstate is made from tungstate and used as a phosphor in industrial Xray screens, fireproof fabrics, and other products. A pigment, tungsten dioxide is used in ceramics or paints because of its yellow richness.
Tungsten Trioxide was used to produce electrochromic and smart windows. These windows are the glass for the electric switch, as well as the light transmission performance and applied voltage change. It is possible to tint windows by changing the amount of light or heat.
Some tungsten oxide can be used to make chemical products like paints and coatings or petroleum industry catalysts. The tungsten metal powder is made from tungsten carbonate, while tungsten metal powder is produced by tungsten metal powder. Cemented carbide of different grades and uses are produced.

Tungsten Trioxide, due to its outstanding electrical and thermal properties, is widely used as a semiconductor electronic package.
