ABSTRACT:
A low-carbon vanadium nitride is prepared in a furnace at an elevated temperature of about 1400.degree. C. under nitrogen atmosphere from a feed material containing a mixture of vanadium oxynitride and carbon. The vanadium oxynitride is prepared by the partial ammonia reduction of a vanadium-containing oxidic compound such as ammonium metavanadate (NH.sub.4 VO.sub.3) or oxides of vanadium such as V.sub.2 O.sub.3 and V.sub.2 O.sub.5.
