Abstract

Aluminum hydroxide gels were prepared by ihe sol-gel method. The role of acid in sols was investigated through the analysis of telling lime and hydrolysis rale. The phase transformation of gels with calcination temperatures was also monitored with X-Ray diffraction.

The gelling times of the aluminum hydroxide sols decreased with the increase of acid content. Exceptionally, the solution peplized with 0.07 HCI/alkoxide molar ratio look longer time than other solutions until the gellation. The hydrolysis rate of aluminum hydroxide was much faster as the acid concentration increased during peptization. In the case of NH4OH as a peptizing agent, there was Ihe lower rate of hydrolysis and thus the more alkoxyl groups were remained in the gel.
