Nanoscale tungsten carbide powders prepared by nanotechnology have very high surface activity, which can significantly reduce sintering temperature, obtain uniform fine crystal structure, and improve the properties of the alloys. Therefore, it has become a research hotspot at home and abroad. The methods of ultrafine/nanometer tungsten-based alloy powder preparation are: high-energy ball grinding, gas evaporation, sol-gel method, freeze-drying method, self-spreading high-temperature reduction method, spray drying - heat reduction method, closed shrinkage epoxidation method, etc.One should be most widely used for spray drying - thermal reduction and high - energy ball milling.China's research in this area has achieved fruitful results.
