Yellow tungsten oxide is a finely divided, yellow crystalline powder. It is produced by roasting ammonium paratungstate at closely controlled temperatures to drive off water and ammonia. Exact time and temperature control determine, to a large extent, the physical characteristics of yellow tungsten oxide.

Tungsten oxide 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. The colour centre, thus formed, shows a slight bleaching with light.

Yellow Tungsten Oxide; Tungsten oxide is used for the production of tungsten metal powder or as compound and pigment for ceramics. Two commercial grades are available: 1. Tungsten Blue Oxide WO2.97 has a deep blue colour. 2. Tungsten yellow oxide WO3 has a yellow to bright green colour. Yellow tungsten oxide (WO3 - YELLOW OXIDE) is a finely

However, it bleaches thermally and in presence of oxidizing atmosphere. The formation of colour-centres is associated with increased electrical conductivity of the film.
