VANADIUM(IV) OXIDE Chemical Properties,Uses,Production

Description

Vanadium (IV) dioxide is a kind of inorganic compound with its chemical formula being VO2. It can undergo a phase transition at a normal temperature (~66 °C). Its electrical resistivity and opacity can also change several fold. These special properties make it have many applications. For example, it can be used in chemical sensors, energy-conserving coatings, transparent conductors and switching materials. It can also be used as a stationary optical shutter, optical modulators, cameras and data storage. Moreover, it can be applied to the missile guidance system due to its infrared modulation capability. It can also be used to make thin films which have been used in electro-optical switches, micro-optical switch, passive smart radiators and sunshields for spacecraft. It can also be used in phase change computing and memory.

Chemical Properties

Blue-black powder. Insoluble in water; soluble in alkalies and acids.

Chemical Properties

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)?.

Uses

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.

Hazard

Toxic and irritating.
