Y2O3　doped　tungsten　powders　were　prepared　by　method　of　spray　drying　combined　with　two-step　hydrogen　reduction　to　fabricate　Y2O3-W　cathode.　The　XRD,　SEM　results　declare　that　by　using　this　kind　method,　the　yttrium-doped　tungsten　powders　had　an　average　size　of　550　nm　with　homogenous　distribution　of　Y2O3　throughout　the　tungsten.　It　is　expected　that　cathode　made　of　this　kind　of　powders　can　provide　good　emission.
