VANADIUM (III) OXIDE Chemical Properties,Usage,Production

Chemical Properties

Black crystals. Soluble in alkalies and hydrogen fluoride; slightly soluble in water.

Uses

Catalyst, e.g., when making ethanol from ethylene.

Uses

Vanadium(III) oxide catalyzes the direct fluorination reactions. It is used in the coating of carbon nanotubes and as an electrode in lithium ion batteries.

Air & Water Reactions

VANADIUM (III) OXIDE undergoes slow air oxidation at room temperature [Kirk-Othmer]. VANADIUM (III) OXIDE does ignite upon heating in air. Slightly soluble in water.

Reactivity Profile

VANADIUM (III) OXIDE is basic. Reacts rapidly with chlorine. soluble in alkalis and in hydrofluoric acid.

Flammability and Explosibility

Non flammable

Safety Profile

Poison by ingestion, subcutaneous, and intratracheal routes. Igmtes when heated in air. When heated to decomposition it emits toxic fumes of VOx. See also VANADIUM COMPOUNDS.
