摘　　要：研究了用喷雾干燥法处理Yb2O3掺杂的氧化锆超细粉的性能。采用LS800型激光衍射粒度分析仪、JB-1型氮吸附比表面仪、Rigaku-DmaxⅡ型X射线衍射仪(XRD)和JSM-6700F型扫描电镜(SEM)分析了喷雾干燥法制备的Yb2O3(Al2O3)-8YSZ超细粉的粒度分布和比表面积,研究了粉末微观形貌特征。结果表明,制备的是球形颗粒、分散性好,晶粒尺寸均匀的超微细2%Yb2O3(Al2O3)-8YSZ(摩尔分数)粉末。The ultra-fine 2mol% Yb2O3 and 8mol% Y2O3 doped ZrO2（8YSZ）powder was treated by Spray Drying Method was analysed. The morphology of the powder was characterised by Rigaku-Dmax Ⅱ high-resolution X-ray diffractometer（XRD） ,JSM-6700F scanning electron microscope（SEM）.Particle size distribution and BET specific surface area was tested by LS800 laser diffractron particle analyzer, Brunauer-Emmett-Teller method. The results show that powder have a good dispersibility, ultra-fine spherical particles,with homogeneous crystal in size.
