Abstract: The theoretical analysis and experimental investigation have been taken for the reduction process of preparation VN with C and V₂O₅. The results show that both direct reduction and indirect reduction take place during the reduction process of V₂O₅, in which the VN formed with high-temperature- nitrogenization changes into VC. With the experimental conditions, the beginning reaction temperature of direct reduction is 656 K, the nitrogenization occurs at 1 160 K, and VN translates into VC at 1 560 K. The indirect reducing reaction is related to the ratio of mixture, with the increase of carbon ratio there occurs increase in possibility of reducing reaction.
