Preparation of vanadium-nitrogen alloy at low temperature by a coupled electric and thermal field

Vanadium-nitrogen alloy was prepared at 900 °C by a coupled electric and thermal field using vanadium pentoxide and carbon black powder as raw materials. The effect of different alternating current densities and reaction time on the material phase and chemical composition of nitridation products was investigated. It was demonstrated that the current densities had a great influence on the formation of vanadium nitride (VN) phase and the content...
