摘　　要：介绍了以ZrOCl_2·8H_2O和Y(NO_3)_3为原料、EDTA为络合剂,采用化学共沉淀法制备3Y-TZP纳米复合粉的技术,用透射电镜分析粉体的形貌、估算粒径,用X射线衍射法分析粉体结构,结果表明经过醇洗+共沸蒸馏处理的粉末粒径比仅用醇洗处理的粉末粒径要小,且分散性最好。The 3Y-TZP nanometer composite powders are prepared with raw materials of ZrOCl_2·8H_2O and Y(NO_3)_3, EDTA as disperser by co-precipitation method. The shape and grain size of powders are observed by means of TEM. The phase of powders are analyzed by means of XRD. It is shown that the grain size of powder by ethanol-washing and co-boiling distillation is smaller than that only by ethanol-washing and has best dispersity.
