Abstract The effects of different Mo-doping on the morphology and grain size of tungsten powder were studied systematically by doping ammonium paramolybdate ((NH4)6Mo7O24) solution into APT. The results show that Mo experiences the transition process of MoO3→MoO2→Mo during the reduction process, and finally exists in the form of elemental Mo; Compared to tungsten powder without doping, the surface topography of Mo-contained tungsten powder becomes irregular; and the average grain size of tungsten powder decreases constantly with the increase of Mo doping content.
