| Abstract：The influences of reaction temperature,content of precipitation agent and dispersing agent on CeO2-ZrO2 solid solution prepared by co-precipitation method was studied,and the solid solution was characterized by TEM and XRD.The results indicated that the even distribution of CeO2-ZrO2 nano-solid solution with particle size about 10 nm could be obtained under the following process conditions such as temperature of reaction 18~25℃,5~6 mol/L NH3·H2O and dispersing agent polyacrylamide. |
