摘　　要：采用电热、冷冻、喷雾干燥法对化学沉淀法制备的ZrO2前驱体进行干燥后,在600℃下保温2h进行煅烧,并对ZrO2前驱体及煅烧产物进行物相表征,对ZrO2煅烧产物形貌及粒度分布进行分析。研究表明,采用不同的干燥方法制备的ZrO2粉体形貌和粒度分布不同,其中喷雾干燥制备的ZrO2粉体分散性最好,粒度分布窄,粒径较小,平均粒径达到85nm。After drying the ZrO2 precursor made by chemical precipitation method using electric heating,refrigerating and spray drying method,a 2 h calcining is done under 600 ℃,phase characterization is done for the ZrO2 precursor and the calcined product,and the appearance and particle size distribution of ZrO2 calcined product are analyzed.According to the study,ZrO2 powders made by different drying methods have different appearance and particle size distribution,in which,the ZrO2 powder made by spray drying offers the best dispersing,narrow particle size distribution,smaller particle size,and the average particle size is up to 85 nm.
