摘要：

New techniques for a solventless TEOS hydrolysis reaction and for inducing rapid homogeneous gelation with syneresis in silica hydrosols are described. The dependency of gelation time and syneresis shrinkage on the conditions at gelation are illustrated, and a reaction mechanism, based on structural considerations, is proposed. Some applications of these novel processes are suggested.
