摘要
采用化学共沉淀法制备了ＺｒＯ_２－ＣｅＯ_２超细粉末。讨论了反应物浓度、反应过程温度、ｐＨ值、灼烧温度对粉末性能参数的影响，获得了加入分散剂的共沉淀反应的优化条件：反应物浓度１．０ｍｏｌ／Ｌ，ｐＨ值１０．０左右，反应温度约４０℃，粉料的灼烧温度８００℃为宜。
The properties of ZrO_2(CeO_2)poweders prepared by coprecipitation were studied. During precipitution process,the state of agglomeration can be controled by high polymer additives instead of alcohol.The effect of the processing condition on the sintering behavior was investigated roughly. The optimal preparing condition of ultrafine powders are proposed.
