Characteristic
Vanadium(III) oxide is the inorganic compound with the formula V2O3. It is a black solid prepared by reduction of V2O5 with hydrogen or carbon monoxide. It is a basic oxide dissolving in acids to give solutions of vanadium (III) complexes. V2O3 has the corundum structure. It is antiferromagnetic with a critical temperature of 160 K. At this temperature there is an abrupt change in conductivity from metallic to insulating.
Chemical formula:V2O3
Molar mass:149.881 g/mol
Appearance:Black powder
Density:4.87 g/cm3
Melting point:1,940 °C (3,520 °F; 2,210 K)
Solubility in other solvents:Insoluble
Magnetic susceptibility (χ):+1976.0·10−6 cm3/mol
Crystal structure:Trigonal (karelianite)
Application
Vanadium(III) oxide catalyzes the direct fluorination reactions. It is used in the coating of carbon nanotubes and as an electrode in lithium ion batteries.
