Tungsten oxide color

Blue tungsten oxide is the product of reductant and tungsten compounds. Composition of blue tungsten oxide is complex, among which there are also intermediate oxides like WO2 and W4. The blue tungsten oxide changes color when it sees light, turning into a light blue. If you put it in an opaque black bag, it will change to its original color. Nano tungsten trioxide is lemon yellow powder, density 7.2-7.4g/cm3, melting point is about 1470 C, boiling point is 1700-2000 C, sublimation is obviously higher than 800 C. Tungsten oxide is used for the production of tungsten metal powder or as compound and pigment for ceramics.

The bronze-colored solid crystallizes in a monoclinic cell. The rutile-like structure features distorted octahedral WO 6 centers with alternate short W–W bonds (248 pm). Each tungsten center has the d 2 configuration, which gives the material a high electrical conductivity. Blue tungsten oxide (BTO) is one of the most important high purity intermediate products used in the manufacture of metal tungsten powder. It’s a kind of finely divided blue-violet crystalline powder.

Due to its rich yellow color WO3 is also used as a pigment in ceramics and paints.

Tungsten Oxide Powder Market by Product Type [ by Formula ( WO2, WO3, W2O5), by Appearance ( BTO, YTO, VTO), By APS ( 0-100 nm, 100 nm-1 um, 1um-100um) by Application ( Color and Pigment, Semiconductor and Electronics, Optics, Chemicals) by Industry Analysis, Volume, Share, Growth, Challenges, Trends and Forecast 2019–2027

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