What is Tungsten Trioxide used for?

Tungsten Trioxide is used for many purposes in industry, such as tungsten and tungstate manufacturing which are used as X-ray screens and for fire proofing fabrics. It is used as a ceramic pigment. Nanowires of Tungsten (VI) oxide are capable of absorbing a higher percentage of the sun radiation since it absorbs blue light.

In everyday life,Tungsten Trioxide is frequently used in manufacturing tungstates for x-ray screen phosphors, for fireproofing fabrics and in gas sensors.  Due to its rich yellow color, WO3 is also used as a pigment in ceramics and paints.
