中文摘要：

本文分别以钛酸丁酯的冰醋酸溶液和四氯化钛的乙醇溶液为钛源,硝酸铝的乙醇溶液为铝源,采用溶胶-凝胶法制备钛酸铝溶胶,通过分析溶胶的流变学特征和显微结构,研究了两种钛源对钛酸铝溶胶可纺性的影响。结果表明:以钛酸丁酯的冰醋酸溶液为钛源,制备的钛酸铝溶胶,由球形胶粒团聚体组成,呈非牛顿型流体的特性,溶胶不具有可纺性;而以四氯化钛乙醇溶液为钛源制备的溶胶,由线型聚合物构成,粘度为18.1~28 Pa.s,属于牛顿型流体,具有很好的可纺性。

英文摘要：

Two kinds of aluminum titanate sols were prepared by sol-gel method using Ti(OC4H9)4-acetic acid solution and TiCl4-ethanol solution as titanium source,Al(NO3)3·9H2O as aluminum source.The effect of two titanium sources on the spinnability of aluminum titanium sols was studied by analyzing the rheological character and microstructures of the prepared sols.The results show that when using Ti(OC4H9)4-acetic acid solution as titanium source,the sol,consisting of spherical colloidal aggregates,is characterized ...
