The tungsten oxides with uniformly grain growth inhibitor elements can significantly improve the distribution of inhibitors in the subsequent WC powders, and finally enhanced the properties of ultra-fine grained cemented carbides. Thus, a new liquid-liquid doping method was used to prepare the tungs...
