| Abstract: | Two kinds of porosity have been found in wet gels prepared by an esterification-controlled hydrolysis: macropores and mesopores. The textural evolution during the during shows that the most dilute gel shrinks the most rapidly. The dynamical part of the Scherer model gives a good account of this observed behavior. |
