Chemische Eigenschaften
Vanadium(IV) Oxide (vanadium dioxide, VO2) is a blue-black solid, having a distorted rutile (TiO2) structure. It can be prepared from the reaction of V2O5 at the melting point with sulfur or carbonaceous reductants such as sugar or oxalic acid. The dioxide slowly oxidizes in air. Vanadium dioxide dissolves in acids to give the stable (VO)2+ ions and in hot alkalies to yield vanadate(IV) species, eg, (HV2O5).
Verwenden
Vanadium(IV) oxide is used in chemical sensors, energy-conserving coatings, transparent conductors and switching materials. It acts as a stationary optical shutter, optical modulators, cameras and data storage. As infrared modulators, it is used for the missile guidance systems. Thin films made up of vanadium dioxide find applications in electro-optical switches, micro-optical switch, passive smart radiators and sunshields for spacecraft.
Definition
ChEBI: Vanadium dioxide is a vanadium oxide.
Hazard
Toxic and irritating.
Flammability and Explosibility
Non flammable
