Vanadium Pentoxide is the most stable of all vanadium compounds. It is an orange solid which is poisonous and when heated loses its oxygen. It is an important industrial chemical which is widely used as a catalyst.

Unlike most metal oxides it dissolves slightly in water to produce a yellow acidic solution. It reacts with alkali to form polyoxovanadates.

Vanadium pentoxide is easily reduced in acidic solutions where the vanadium (V) state is reduced to the stable vanadium(IV) state.

Uses for Vanadium Pentoxide:

  • In ceramic industry.
  • In the production of ferrovanadium.
  • In the commercial manufacture of sulphuric acid.
  • As a catalyst in many chemical manufacturing processes.
  • As a detector material in thermal imaging equipment.
  • In the production of vanadium redox batteries.
  • In the synthesis of both maleic and phthalic anhydrides.

Vanadium pentoxide is used in the industries of enamelling, electrics and electronics, metallurgy, glass, catalysts, petrochemistry, and paint, and ceramics. It is also used as a corrosion inhibitor in industrial processes for the production 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 photographic 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
