Preparation of Sb-doped SnO2 Ultrafine Powder via Oxidative-coprecipitation
氧化共沉淀制备Sb2O5掺杂的超细SnO2

Preparation of ultrafine powder of SnO2 doped with antimony by the oxidative-coprecipitation method is reported. The product was characterized by DTA-TG, XRD and TEM. The results showed that the grain size of SnO2 increased with heat-treatment temperature, Sb being doped with Sb2O5, the normal SnO2 crystaline structure was kept the same, but the growth of SnO2 powder was retarded, doping with Sb2O5 can increase more significantly the conductivity of SnO2 ultrafine powder.
