Tungsten Trioxide Application

Tungsten Trioxide Picture

Effects of Exposure:

Tungsten trioxide is used for many purposes in everyday life. It is frequently used in industry to manufacture 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.

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. 2010- AIST reports a quantum yield of 19 % in photocatalytic water splitting with a caesium-enhanced tungsten oxide photocatalyst.
