On the carbonitrothermic reduction of vanadium pentoxide

Abstract

Vanadium nitride was prepared by heating a mixture of vanadium pentoxide and graphite powder under a flowing nitrogen atmosphere. The resultant nitride was evaluated by powder X-ray diffraction and chemical analysis. The effects of various experimental parameters, such as oxide-to-carbon ratio, nitrogen flow rate, nitriding temperature and time, compacting pressure, etc., on the extent of nitridation as well as the purity of the vanadium nitride, were studied.
