Method for producing nano-sized vanadium carbide powder
The invention relates to a method for producing nano-sized vanadium carbide powder, belonging to the technical field of preparing ceramic powder. The method comprises the following processes: (1) mixing a vanadium source, a carbon source and an auxiliary into a solution according to a certain proportion; (2) heating the solution, so that the solution is volatilized, concentrated and decomposed to obtain precursor powder containing the vanadium source and the carbon source; and (3) reacting the precursor powder for 1-5 hours at the temperature of 700-1300 DEG C under certain atmosphere. The method is simple in technology, low in cost, and easy to industrialize, and the obtained vanadium carbide powder has a particle size of less than 50nm, and good dispersity.
