摘　　要：以纯铟、SnCl4·5H2O为原料,采用络盐法制备了纳米晶的铟锡氧化物(ITO)粉末。通过对铟锡复合络合盐(NH4)1.91(In0.91Sn0.09)Cl5·?H2O的制备研究,充分证实了反应初始溶液中络离子的存在。研究了铟离子总浓度对ITO粒径的影响,结果表明:由于络离子的存在控制了游离In3+的浓度,从而可以在一定浓度范围内增加铟离子总浓度而达到提高产量的目的。通过XRD和激光粒度仪对ITO粉末进行了表征。Used complex salt method,indium tin oxide（ITO） nanocrystalline powders was prepared by pure metal indium and SnCl4·5H2O as raw materials.The complex salt crystals（NH4）1.91（In0.91Sn0.09）Cl5·？H2O was synthesized in the experiment,which proved the formation of complex ion in the reaction solution.The influence of indium ion total concentration on the particle size of ITO powder was research.The result indicated that the existing of complex ion decreased the concentration of dissociatived In3＋ and Sn4＋,accordingly,it was possible to increase the output of ITO by increasing the indium ion total concentration in definite extension.ITO nanocrystalline powders was characterized by XRD and laser particle size analyzer.
