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.
