以共沉淀结合喷雾干燥的方法制备了纳米级的ＹＴＺ粉料（以Ｙ２Ｏ３稳定的ＺｒＯ２），讨论了反应物浓度、碱度、烧结方法、成粒方法、烧结条件等对粉料的影响．热分析和ＸＲＤ（Ｘ－射线衍射）分析显示，当温度从常温升至７００℃，粉料经历了由无定形向四方相、单斜相晶体的转变，相变温度分别是４５０、７００℃．对烧结过程的研究发现，在３００℃处并非为简单的失水过程而是相转变．用ＴＥＭ（透射电子显微镜）观察了粉料团聚体的形貌、尺寸，ＴＥＭ及Ｘ射线线宽法确定晶粒的大小约２０ｎｍ；ＢＥＴ法测得其比表面积最高可达７９．５ｍ２／ｇ．
The effects of reactant concentration, alkalinity, sintering method, granulation method and sintering conditions on the powders were investigated by coprecipitation combined with spray drying. Thermal analysis and XRD (X-ray diffraction) analysis showed that when the temperature was raised from normal temperature to 700 ℃, the powder underwent a transition from amorphous to tetragonal and monoclinic phase with the transformation temperature being 450 and 700 ℃, respectively. A study of the sintering process found that phase transformation was not at 300 ° C for a simple water loss process. The morphology, size, TEM and X-ray width of the aggregates were observed by TEM (transmission electron microscopy) to determine the size of the grains was about 20nm; BET specific surface area measured by BET method up to 79.5m2 / g.
