Scandium　oxide-doped　tungsten　powders　were　prepared　by　a　new　method　of　spray　drying　combined　with　two-step　hydrogen　reduction.　The　particle　size　of　doped　tungsten,　powder　morphology,　and　distribution　of　doped　scandium　oxide　were　characterized　by　scanning　electron　microscopy,　X-ray　diffraction,　and　laser　diffraction　particle　size　analysis.　Experimental　results　indicated　that　the　predecessor　powders　prepared　by　spray　drying　were　spherical　in　shape.　Two　compounds,　WO3　and　Sc2W3O12,　in　the　raw　powder　calcined　at　600　degrees　C　were　transformed　into　metallic　tungsten　and　scandia　after　reduction　at　850　degrees　C　by　hydrogen　for　1　h.　The　scandia-doped　tungsten　powders　obtained　had　an　average　size　of　950　nm　and　scandium　oxide　was　distributed　evenly　throughout　the　tungsten　powder.　The　mechanism　of　reduction　of　the　doped　tungsten　oxide　is　discussed　in　this　paper.
