The Major Use of Vanadium Pentoxide

Vanadium Pentoxide Flake vs Vanadium Pentoxide Powder

The major use of vanadium pentoxide 99% is in the production of metal alloys. Iron–vana- dium and aluminium–vanadium master alloys (e.g. for automotive steels, jet engines and airframes) are produced preferably from vanadium pentoxide fused flakes because of the low loss on ignition, low sulfur and dust contents, and high density of the molten oxide compared with vanadium pentoxide powder.

Vanadium pentoxide catalyst

Vanadium pentoxide is also used as an oxidation catalyst,in heterogeneous and homo- geneous catalytic processes for the production of sulfuric acid from sulfur dioxide, phthalic anhydride from naphthalene or ortho-xylene, maleic anhydride from benzene or n-butane/ butene, adipic acid from cyclohexanol/cyclohexanone, acrylic acid from propane and acetaldehyde from alcohol. Minor amounts are used in the production of oxalic acid from cellulose and of anthraquinone from anthracene. Vanadium pentoxide 99.5% has not found any significant uses in microelectronics but does have some applications in cathodes in primary and secondary (rechargeable) lithium batteries and in red phosphors for high-pressure mercury lamps and television screens. Vanadium pentoxide is used in the industries of enamelling, electrics and electronics, metallurgy, glass, catalysts, petrochemistry, and paint and ceramics.

Vanadium Pentoxide Used As Corrosion Inhibitor

I t is also used as a corrosion inhibitor in industrial processes for the produc- tion of hydrogen from hydrocarbons, as a coating for welding electrodes, as ultraviolet absorbent in glass, as depolariser, for glazes, for yellow and blue pigments, as a photo- graphic developer, and in colloidal solution for anti-static layers on photographic material. It is also used as starting material for the production of carbides, nitrides, carbonitrides, silicides, halides, vanadates and vanadium salts .
