Scandia　and　rhenium　doped　tungsten　powders　were　prepared　by　solid-liquid　doping　combined　with　two-step　reduction　method.　The　particle　size　of　doped　tungsten　and　distribution　of　scandia　and　rhenium　were　studied　by　SEM,　EDS,　XRD　and　granularity　analysis.　Experimental　results　showed　that　scandia　distributed　evenly　on　the　surface　of　tungsten　particles.　Addition　of　scandia　and　rhenium　decreased　the　particle　size　of　doped　tungsten,　and　the　more　the　content　of　scandia　and　rhenium,　the　smaller　the　doped　tungsten　particles.　Tungsten　powders　doped　with　3　%　Sc2O3　and　3　%　Re　(mass　fraction)　had　an　average　size　of　about　80　nm　in　diameter.　The　mechanism　of　the　decrease　in　the　tungsten　particle　size　was　discussed.
