摘　　要：以SnCl4·5H2O和SbCl3为原料,通过正交实验并借助于XRD,TEM等手段,研究了前驱物浓度、反应温度、保温时间和氨水滴加速率等工艺因素对水热合成锑掺杂SnO2纳米粉体的影响,探讨了不同分散处理工艺对纳米粉体分散性的影响。Nanocrystalline rutile-tin dioxde powders were prepared by a hydrothermal synthesis of a mixed ethanol solution of SnCl4 . 5H(2)O and SbCl3. The influences of the-dripping velocity of ammonia, reaction temperature and time, the and concentration of starting materials on the synthesis of Sb-SnO2 nanopowders were studied by orthogonal design and by means of XRD and TEM. The influence of various dispersing techniques on the dispersion of Sb-SnO2 nanopowders were also discussed.
