In this paper, nanopowders of rare earth oxides and tungsten were prepared and 0-3 type nano-composit rare earth tungsten thermionic emission materials were fabricated with novel technics. The raw material selection, preparation technic parameter, structure, physical and chemical characteristic, the rare earth distribution and the emission behavior were studied. The influence between the active layer and the thermionic emission performance, rare earth elements diffusion and distribution along depth were investigated in detail. The surplus RE formation and the electron transfer were discussed in theoretically. The thermionic emission current density of the single surplus RE on the active layer was educed. We adopted "liquid-liquid mixing, freeze-drying and two stage-reduction" working step firstly to produce the RE-W nanopowders including La-W powder, Ce-W powder and Y-W powder.
