A novel process for synthesizing ceramic powders in molten salt was introduced in this paper. Dissimilar to traditional mechanochemical process, the novel process is based on chemical reaction in liquid phase (molten salt). The reaction temperature to synthesize tungsten carbide in molten salt could be reduced to 1000°C compared with traditional solid state methods. Results in this paper showed that nano W2C powder could be successfully synthesized through this method. The mechanism of the reaction in molten salt was discussed finally.
