摘要
用水解沉淀法和中和沉淀法两种工艺制备了水合氧化锆凝胶,并与经乙醇脱水处理后的水合氧化锆凝胶的形貌、热性能、相态以及红外吸收光谱作了比较。
Two different routes, hydrolysis and precipitation, are described to prepare hydrous zircoina gel.The characteristics of the hydrous zirconia gel before or after dehydration with alcohols have beendetermined by TEM, DTA, XRD and IR. The results show that the hydrous zirconia gel obtainedfrom precipitation is amorphous and crystalline for hydrolysis. The OH groups remaining in struc-ture of hydrous zirconia gel is hard to remove.
