The gelation of aluminum hydroxide sols obtained from aluminum sec-butoxide has been studied as a function of the conditions of preparation, including pH, temperature, and time of aging. It has been found that stable sols can easily be obtained by processing at any temperature between 20 degree C and 90 degree C beyond a molar proportion of 0. 28 HNO//3. The corresponding gels are suggested to have a boehmite-like structure.
