In　order　to　improve　the　mechanical　strength　and　machining　properties　of　Scandia　Doped　Dispenser　(SDD)　cathodes　when　they　are　applied　into　Vacuum　Electron　Devices　(VEDs),　an　effort　has　been　expended　to　increase　the　W　grain　sizes　while　maintaining　the　uniform　doping　of　nanosized　Scandia　particle.　By　an　improved　liquid-solid　(L-S)　doping　process,　powders　composed　of　W　grains　of　about　1-2　micron　in　diameters　with　uniformly　distributed　nanosized　scandium　oxide　particles　have　been　fabricated.　Cathodes　constructed　by　above　powders　exhibited　better　properties　in　machining　operations　like　lathing,　and　similar　emission　characteristics　to　that　of　SDD　cathodes　made　from　the　powders　with　liquid-liquid　doping　methods.
