Characteristic
Vanadium(IV) oxide or vanadium dioxide is an inorganic compound with the formula VO2. It is a dark blue solid. Vanadium(IV) dioxide is amphoteric, dissolving in non-oxidising acids to give the blue vanadyl ion, [VO]2+ and in alkali to give the brown [V4O9]2− ion, or at high pH [VO4]4−.
Chemical formula：VO2
Molar mass：82.94 g/mol
Appearance：Blue-black powder
Density：4.571 g/cm3 (monoclinic)
4.653 g/cm3 (tetragonal)
Melting point：1,967 °C
Magnetic susceptibility (χ)：+99.0·10−6 cm3/mol
Crystal structure：Distorted rutile (<70 °C, monoclinic)
Rutile (>70 °C, tetragonal)
Application
Vanadium dioxide stands out in the material world for its rapid and abrupt phase transition at a temperature of 68 °C. The electric conductivity of vanadium dioxide makes it have wide application potential in optical devices, electronic devices and optoelectronic devices.
