Vanadium

Vanadium is a hard, silvery grey, ductile and malleable transition metal. The elemental metal is rarely found in nature.

Approximately 85% of vanadium produced is used as ferrovanadium or as a steel additive. The most common oxide of vanadium, vanadium pentoxide V2O5, is used as a catalyst in manufacturing sulfuric acid by the contact process and as an oxidizer in maleic anhydride production. The Vanadium redox battery, a type of flow battery, is an electrochemical cell consisting of aqueous vanadium ions in different oxidation state.

Roasted Vanadium compound, Slag, Fly ash containing Min 15% V2O5 are used to make Vanadium Pentoxide & FeV.
