• 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.
• Uses: Vanadium(IV) oxide is used in chemical sensors, energy-conserving coatings, transparent conductors and switching materials.
