摘　　要：通过化学成分分析、X射线衍射和扫描电镜观察,对比分析了洗涤介质对共沉淀法制备Mg-PSZ粉体的物质损失、晶粒大小和显微结构的影响。结果表明,先采用氨水溶液洗涤、再采用酒精洗涤的粉体,物质损失量少,二次粒度小且颗粒分布较为均匀。The effect of washing mediums on the material loss, grain size and microstructure of Mg-PSZ powder prepared by coprecipitation method was investigated by means of chemical composition analysis, X-ray diffraction analysis （XRD） and scanning electron microscopy （SEM）. The results show that the powder washed by thin aqueous ammonia first and then by alcohol has less material loss, smaller secondary grain size and more uniform distribution.
