Abstract

Alumina sols made by the hydrolysis of aluminum sec-butoxide in an acidic medium have been found to show behavior during drying and aging which appears similar to that reported for gels in a number of clay-water systems. Structural and phenomenological characteristics of these two classes of materials are compared. The extension to aluminum hydroxide systems of the models proposed to explain the gelation of clay sols are discussed, and a model is presented to describe the gelation behavior of aluminum hydroxide sols.
