Tungsten Trioxide Uses

Tungsten trioxide is widely used for many purposes in life. It is frequently used in industry to manufacture tungstates for fireproofing fabrics, for x-ray screen phosphors and in gas sensors. WO3 is also used as a pigment in ceramics and paints due to its rich yellow color.
 
In recent years, tungsten trioxide has been employed in the production of electrochromic windows, or smart windows. These windows are electrically switchable glass that change light transmission properties with an applied voltage. This allows the user to tint their windows, changing the amount of heat or light passing through.
 
The composite showed a modest hydrogen production performance. In 2013, highly photocatalytic active titania/tungsten (VI) oxide/noble metal (Au and Pt) composites toward oxalic acid were obtained by the means of selective noble metal photodeposition on the desired oxide's surface (either on TiO2 or on WO3).
