摘要: 以金属铟和锡为原料,于碱性环境240℃水热合成12h并经500℃煅烧2h得到了 粒径为70±10nm,比表面积为11 m2/g的高纯氧化铟锡(ITO)粉末.由SEM、激光粒度测试 仪和BET三种方法分析得到的粉末平均粒径相吻合,证明制备的粉末是单分散状态的.研究 还发现,提高铟锡初始浓度和氢氧化钠过量浓度均有利于小粒径单分散ITO粉末的制备,但 过高的氢氧化钠过量浓度会使粉末出现团聚.

Abstract: Monodispersed tin doped indium oxide (ITO) powders with 70±10nm particle size and 11 m2/g special surface area were prepared by a hydrothermal process at 240℃ for 12h, and calcination
process at 500℃ for 2h, by using indium and tin metals as raw materials. X-ray diffractometry, scanning electron microscopy, Brunauer-Emmett-Teller analysis confirm that the as-prepared powder
is monodispersed and increasing the NaOH excess concentration (from 0 to 2.0mol/L) and the initial indium and tin concentration (from 0.25mol/L to 1mol/L) is benificial to preparing monodispersed ITO
powders with small particle sizes.

Key words: doped indium oxide, nanometer powder, hydrothermal, monodispersed
