THERMODYNAMIC ANALYSIS OF PREPARATION OF METALLIC VANADIUM(V), VANADIUM CARBIDE (VC) AND VANADIUM NITRIDE (VN)

The thermodynamic characteristics of (V-O-C-N) and (V-O-H-N) systems are analyzed and discussed by means of thermodynamic method.The results obtained provide the theoretical basis for preparation of metallic vanadium, its carbide and nitride when carbon or hydrogen is used as reductant and vanadium oxides as raw materials.
