Abstract

Vanadium nitride, prepared by carbonitrothermic reduction of a V2O5 + C mixture at a temperature of 1500 degreesC under continuous nitrogen flow, wasthermally decomposed to metallic vanadium. The extent of removal of nitrogen from VN was found to depend upon temperature, time and reduced pressure. A portion of the residual oxygen and carbon, present in VN, was also removed, in the form of CO, during denitrogenation. The optimum decomposition temperature, time and pressure were 1750 degreesC, 1 h and 0.05 Pa for a charge of 500 g. The vanadium, obtained at the end of the pyrovacuum heating, is suitable for catalytic applications in industrial processes.
