Mo2C powders were prepared at lower temperature using molten salt method with Mo-C mixed powders treated by mechanical activation. Meanwhile, the influences were investigated of milling （i. e. , mechanical activation） time, molten salt temperature and heat preservation time on the microstructure and morphology of the samples. The results indicate that under the optimized conditions of 10 h milling,900 ℃ molten salt temperature, 1 h heat preservation, Mo2C powders can be obtained with particle size of about 500 nm. It is found that prolonging milling time can promote the subsequent formation reaction of Mo2 C in molten salt and help to reduce molten salt temperature of the subsequent reaction to ensure energy conservation.
