Abstract: Nanosized hydrous-zirconia sol was prepared by heating a zirconyl chloride solution with an alcohol-water mixture as the solvent and hydroxypropyl cellulose (HPC) as a dispersant in microwave oven. The sol could be transformed into m-ZiO2 and a litde of t-ZrO2 powders after being dried and calcined.The mean particle sizes of ZrO2·nh2O increase as ZrOCl2 concentration increases.The effects of HPC concentration and heating means on size and size distribution of resulting particles were analyzed.

摘要: 加热醇水混合物为溶剂、羟丙基纤维素(HPC)为分散剂的氧氯化锆水溶液,快速制备纳米级水合氧化锆溶胶,经烘干、煅烧获得单斜相和极少量四方相的ZnO_2纳米粉体.随ZrOCl_2·8H_2O浓度的增加(~0.3 mol·L~(-1)),水解产物的粒径增大;并分析了分散剂加入量和加热方式对产物粒径及分布的影响.
