以铟锭、SnCl4·5H2 O、SbCl3和尿素为主要原料，按In2 O3∶SnO2∶Sb2 O3的质量比为95∶5∶0、93∶5∶2、90∶5∶5制备前驱体，使用水热法制备锑掺杂In（ OH）3纳米粉末，然后马弗炉中煅烧得到锑掺杂ITO。利用X射线衍射（ XRD）、透射电子显微镜（ TEM）、热重?差热（ TG／DSC）、红外光谱和分光光度计等手段分析研究不同制备条件对产物的影响。结果表明：温度是水热反应的决定性因素，水热温度为160℃时制备的水热产物为立方纯相；尿素用量与阳离子浓度对水热结果的影响不明显；添加适量分散剂PVP可以减少团聚，得到均匀分散的产物；锑的掺杂使ITO对红外线的阻隔波段有所变化。

Using indium ingot, SnCl4 ·5H2 O, SbCl3 and urea as raw materials, precursors were synthesized with the mass ratio of In2O3∶SnO2∶Sb2O3 as 95∶5 ∶ 0, 93∶5∶2 and 90∶5∶5, respectively, and antimony?doped In(OH)3 nanopowders were prepared by a hydrothermal process. Then, In(OH)3 was transferred into antimony?doped ITO after calcination in a muffle furnace. The effects of synthesizing parameters on product properties were investigated by XRD, TEM, FTIR, TG?DSC and spectrophotometry. The results show that, the hydrothermal temperature is the decisive factor and powders of pure cubic phase can be synthesized at 160 ℃. However, the urea dosage and cation concentration haven′t significant influence on hydrothermal products. Aggregation level can be reduced and products with homogeneously dispersed particles can be obtained in the presence of an appropriate amount of dispersant PVP. Compared with ITO, there is a variation on the infrared barrier bands of antimony?doped ITO.
