How Is Vanadium Nitride Produced

We all know that vanadium nitride is a better steelmaking additive than high vanadium iron, using vanadium nitride as an additive, the nitrogen component of vanadium nitride can promote the precipitation of vanadium after hot processing, so that the precipitated particles are smaller, so as to better improve the weldability and formability of steel. It is used as a raw material for cemented carbide to produce wear-resistant and semiconductor films. It is a new and efficient vanadium alloy additive, which can be used to produce high-strength low-alloy steel products such as high-strength welded steel bars, non-quenched and tempered steels, high-speed tool steels, and high-strength pipeline steels. Compared with ferrovanadium, vanadium nitrogen alloy can strengthen and refine the grain more effectively, saving 30%~50% of vanadium compared with the use of ferrovanadium, which has a great effect on improving the strength of steel and reducing the cost of steelmaking. It can also be used as a raw material for cemented carbide to produce wear-resistant and semiconductor films. So how is vanadium nitride produced, let me tell you

1. Vanadium nitride can be prepared by mixing stoichiometric carbon and vanadium pentoxide fully and carrying out a reduction nitriding reaction at 1250 °C in a chlorine atmosphere. It can also be prepared by reacting nitrogen-hydrogen mixture with vanadium tetrachloride at 1400~1600 °C; or prepared by reacting ammonia (NH3) with ammonium metavanadate (NH4VO3) at 1000~1100 °C.

2. Adopt the reduction method. Vanadium nitride can be prepared by mixing stoichiometric carbon and vanadium pentoxide fully and carrying out a reduction nitriding reaction at 1250 °C in a nitrogen atmosphere. It can also be prepared by reacting nitrogenhydrogen mixture with vanadium tetrachloride at 1400~1600 °C; or prepared by reacting ammonia (NH3) with ammonium metavanadate (NH4VO3) at 1000~1100 °C.
