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.

本文采用细化显微组织的新工艺，制备了纳米稀土钨粉末和0-3型纳米复合稀土钨热电子发射材料，探讨研究其原料选择、制备工艺及参数、结构特征、物理和化学特性、稀土分布均匀性、以及热电子发射特性；系统研究了稀土元素的高温扩散情况、高温状态下活性层中稀土的纵向深度分布、以及表面活性物质和活性层厚度对热发射性能的作用；从理论上分析阐释了超额稀土的形成及其电子的传递过程；并从理论上推导了活性层中单个超额稀土的热电子发射电流密度。
