Application
Vanadium(IV) oxide, with the chemical formula VO2, is a versatile inorganic compound notable for its ability to undergo a phase transition around 66 °C, resulting in significant changes in electrical resistivity and opacity. These unique properties lend it to a wide array of applications, including its use in chemical sensors and energy-conserving coatings. Vanadium(IV) oxide serves as an essential component in transparent conductors and switching materials, and functions effectively as a stationary optical shutter and in optical modulators. Moreover, it plays a pivotal role in cameras and data storage and is a critical element in infrared modulators for missile guidance systems. Thin films of this compound find use in electro-optical switches, micro-optical switches, passive smart radiators, and sunshields for spacecraft. Additionally, it is employed in phase change computing and memory technology. As a blue-black powder, vanadium(IV) oxide is insoluble in water but soluble in alkalies and acids, further enhancing its applicability across different industries.
