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
