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.
