Description and Uses

Vanadium pentoxide is a yellow to red colour solid and is odourless. Vanadium pentoxide dust is the particulate form of a non-combustible, odourless, yellow-orange or dark grey crystalline solid.
On decomposition by heating, vanadium pentoxide produces toxic fumes. Vanadium is widely distributed in the Earth’s crust in a wide range of minerals and in fossil fuels. Vanadium pentoxide, the major commercial product of vanadium, is mainly used in the production of alloys with iron and aluminium. It is also used as an oxidation catalyst in the chemical industry and in a variety of minor applications.

In the production of high-strength steel alloys; catalyst in oxidation reactions; in pesticides; in dyes and inks.
