Monodispersed Tin Doped Indium Oxide Nanometer Powders Prepared by Hydrothermal Method

ZHU Gui-Sheng, XU Hua-Rui, LIAO Chun-Tu (Guilin University of Electronic Technology, Guilin 541004, China; Liuzhou China-tin Group Company Ltd., Liuzhou 545006, China)  
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.
