More info

Tungsten Trioxide, or tungsten (VI) oxide or tungstic anhydride, is a thermally stable, water-insoluble tungsten compound. It is a yellow crystalline solid that changes to green or deep blue when exposed to varying temperatures and humidity levels. This color change is accompanied by an increase in electrical conductivity. These unique properties make WO₃ highly valuable for applications such as smart windows and electronic devices

Tungsten Trioxide (WO₃) Powder Applications

It can be reduced by hydrogen to obtain metal tungsten.
It can be mixed with carbon and other metals to form a hard alloy.
It can be reacted with various metals or non-metals to form tungstates.
It can be used as a pigment in ceramics and paints, giving them a yellow or green color, and enhancing their thermal stability and chemical resistance.
It can be used as a catalyst or a catalyst support in various reactions.
It can be used as a fire retardant in plastics, rubber, textiles, and wood, and reduce the flammability and smoke emission of the materials.
