Application

Tungsten(IV) oxide, a bronze-colored solid known for its distorted octahedral structure and high electrical conductivity, is primarily used in the production of tungsten and tungstates, as well as in various industrial applications including alloys, fire-proofing fabrics, and ceramic pigments. Its significant role extends to the study of chromism, photocatalysis, and sensing capabilities. Additionally, when associated with rhenium trioxide particles, it aids in the detection of protonatable, radical, and precharged species through laser desorption ionization techniques. The preparation of Tungsten(IV) oxide, involving the reduction of WO3 using tungsten powder at high temperatures, also offers insights into its catalytic properties, with intermediate phases such as W18O49 highlighting its mixed valence characteristics.
