Abstract：The spherical cast tungsten carbide powder is a kind of new potential wear-resistance ceramic material. The chemical composition，morphology，microstructure，phase composition，micro-hardness，flowability，loose density and other characteristics of spherical cast tungsten carbide powders prepared by different methods were investigated. The results indicate that，compared with plasma re-melting spheroidizing and induction re-melting spheroidizing，the deviation value between the total carbon content and the theoretical carbon content of spherical cast tungsten carbides fabricated by plasma rotation electrode atomization method is the smallest，and the content of free carbon and impurities are the lowest. Furthermore，the corresponding powder particles fabricated by plasma rotation electrode atomization method are denser，the eutectic microstructure is finer and microhardness is higher than those fabricated by other methods. Spherical cast tungsten carbides fabricated by induction re-melting spheroidizing have the best flowability and the highest loose density.
