What is Tungstentrioxide?
Tungsten Trioxide is a light-yellow triclinic powder. If the temperature rises above 740degC it becomes orange tetragonals crystals 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 not soluble with water or other inorganic acid except hydrofluoric. It can be dissolved into a hot, concentrated sodium hydroxide mixture and ammonia in order to create soluble tungstate. When the temperature is above 650°C, it can reduce by H2, and at 10001100°C by C.
Tungsten Trioxide Application:

Tungsten Trioxide is widely used in the daily life. The tungstate is commonly used in the production of industrial X-ray screens phosphors, and fireproof fabrics. Due to the yellow color of tungsten, it is used as a paint and ceramic pigment.
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 the 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-oxide intermediate is a product that is widely used for the production and use of metal tungsten. 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.
