The Effect of Catalysts on TEOS Hydrolysis-Condensation Mechanism

Lin Jian

Abstract

SiO2 gels were prepared by Sol-Gel processing, the influence of catalysts on the hydrolysiscondensation and structure of the gel was studied. The radius of negative ions determines thehydrolysis-condensation mechanism. Different catalysis ways and catalyst concertration, pH value,water content have great influence on the gelation time and the structure of SiO2 gel.
