摘要
将SnCl2·2H2O和SbCl3分别溶解在无水乙醇中,再将SbCl3乙醇溶液分散到SnCl2乙醇溶液中,蒸干后得到醇盐粉体,然后通过直接煅烧醇盐的方法制备了纳米级ATO粉体,运用XRD、DSC等手段对制得的ATO粉体进行了表征,考察了Sb掺杂量对所得纳米粉体导电性能的影响,研究发现,当锑在ATO粉体中的摩尔比为6%时,电阻率最小为11.42Ω·cm;当掺杂量为15%时,制得的粉体粒径主要分布在50nm-100nm范围内。
The ATO nanoparticles have been synthesized by simple direct calcining the alkoxides with the raw materials of SnCl2·2H2O and SbCl3 in this study. A certain amount of them are dissolved in Ethanol and then the solution is evaporated. The alkoxides powders are obtained, then dried and calcined. The ATO powders have been characterized by means of XRD and DSC. Besides, the influence of Sb doped amount on its electrical resistivity has been discussed and the optimizing value of doping 6% Sb has the lowest electrical resistivity of 11.42 Ω·cm. The particle size distribution is mainly located in 50-100 nm range when the Sb doped amount is 15%.
