摘要： 报道了用溶胶-凝胶法制备二氧化钛薄膜过程中钛酸丁酯[Ti(OC4H9)4]水解特性的研究结果，给出了体系的酸碱度(酸催化或者碱催化)、添加乙酰丙酮(AcAc)和硝酸银(AgNO3)对Ti(OC4H9)4-C2H5OH-H2O体系粘度变化和凝胶化时间的影响，发现AgNO3对该体系溶胶有非常明显的稳定作用.

Abstract: Hydrolysis characteristics of Ti(OC4H9)4 in the Ti(OC4H9)4-C2H5OH-H2O system were investigated for the preparation of TiO2 thin films via the sol-gel process. Experimental results are given about the effects of the system acidity (or basicity) and the addition of acetylacetone and AgNO3 on the viscosity and gelation time of the system. It was found that the introduction of AgNO3 can greatly improve the stability of the sols and prolong the gelation time besides adjusting pH and adding acetylacetone
