Abstract
In the present work a study of the gel formation kinetic has been carried out by NMR. We show that applying ultrasounds to the mixture TEOS+H2O multiplies concentration of condensed species with regards to the classic obtained in alcoholic solution. This difference increases with increasing pH of the hydrolysis water.
