摘要：以SnCl₄·5H₂O和SbCl₃为原料，用醇盐水解法制备了纳米掺 锑氧化锡(ATO)导电粉体。用正丁醇—二甲苯的混合溶剂共沸蒸馏、有机 脱水剂以及其它方法对前驱体胶态沉淀进行脱水处理，以消除粉体团聚。 运用 XRD、TEM、BET 等手段对粉体进行表征，比较了各种脱水处理 方法对 ATO 纳米导电粉体的粒度、团聚度、晶粒生长以及电阻率的影 响。结果表明，混合溶剂共沸蒸馏处理以及有机脱水剂是比较有效的脱 水方法，可以用来制备比表面积大（85.32 m²·g ^-1）、团聚小、电阻率低 的纳米 ATO 导电粉体。

Abstract: Conductive antimony-doped tin oxide(ATO) ultra-fine powder is prepared by hydrolysis of alkoxides, using SnCl₄·5H₂O and SbCl₃ as raw materials. In order to eliminate agglomeration, ATO precursor precipitations are treated by n-butanol/xylene mixed solvent heterogeneous azeotropic distil lation processing, organic dehydrating agent and other dehydrating processes. The influences of different dehydrating methods on the properties of powder, such as particle size, agglomeration, specific surface area, and resistance ,are investigated by means of XRD, TEM, BET, and so on . The results show that n-butanol/xylene mixed solvent heterogeneous azeotropic distillation process ing and organic dehydrating agent can dehydrate effectively , and produce powder with large surface areas, about 85.32 m²·g ^-1, low agglomeration and good conductivity.
