Other Experimental

Has corundum (Al2O3) structure; air oxidation proceeds slowly at ambient temperatures but oxidation by chlorine at elevated temperatures to give VOCl3 and V2O5 is rapid;On exposure to air it is gradually converted into indigo-blue crystals of V2O4.;Enthalpy of formation at 298.15 K: -1218.8 kJ/mol; molar heat capacity at 298.15 K: 103.2 J/mol K;Within tissues in organisms, V3+ and V4+ predominate because of largely reducing conditions; in plasma however, which is high in oxygen, V5+ is formed.;Vanadium trioxide undergoes slow air oxidation at room temperature. It does ignite upon heating in air. Reacts rapidly with chlorine.
