Carbothermal Reduction and Nitride Preparing for Vanadium Nitride via One-step Method
In this paper, the producing process of using V2O3 as raw material to obtain vanadium nitride was analyzed through the means of thermodynamic. The analysis shows that conversion follows the principle of reduction step by step in the conversion process of V2O3. The temperature of the reaction system has prominent influence on the nitrogen content of products, and the reaction is very sensitive to temperature. As raising temperature, the fine grain structure of the nitrides is more evident, and the grain size of nitridcs increases. At 1703K, the nitrogen content of the products tended to be constant after soaking over 3 hours.
