Abstract：A liquid chemical precipitation process of preparingIn2O3 nano-scale powders in certain experimental conditions is displayed．In this processpure indium（In） and HNO3 is used as starting materials and the gelatin as dispersant．T he structural properties of In2O3 are characterized by many experimental methods such as chemical analysis、XRD、T EM and BET．T he analyzed results show that In2O3 produced by chemical precipitation process is very pure and monophase spherica-l like nano-scale powders with good dispersity and itʾs average size is less than 30nm．
Keywords：nanometer In2O3；chemical precipitation process； structural characerition
