Fabrication of Vanadium Nitride by Carbothermal Nitridation Reaction

Vanadium nitride is produced from V2O5 by carbon-thermal reduction and nitridation. When the sintered temperature is above 1273K, VN can be formed, and the nitrogen content of the products increased with the firing temperature raised, and then is the largest when the sintered temperature is 1573K. The C/V2O5 mass ratio of the green samples is the other key factor affecting on the nitrogen contents of the products. The nitrogen content of the products reaches the most when the C/V2O5 mass ratio is 0.33, which is the theoretical ratio of the carbothermal nitridation of V2O5.
