Abstract

Silica aerogels obtained by the supercritical drying of wet gels prepared by hydrolysis and condensation of alcoholic mixture of Si(OC₂H₅)₄ (tetraethoxysila- ne- TEOS) and water were studied using SAXS, BET and density measurement. Main reason for the interest in the research of the materials prepared from the alcoxides by sol-gel methods is that the liquid state enables manipulation on a molecular level. This permits structural modifications and optimizing the conditions for the further conversion of the gel into glasses and ceramics.
