- Abstract:
-
Ethyl orthosilicate (TEOS) is used as the main raw material, ethanol as solvent, hydrochloric acid or ammonia as catalyst to prepare silicate gel. The mechanism of sol-gel reaction and the effects of catalyst, water, solvent and reaction temperature on gelling time, viscosity and structure of gel were discussed. The two-step Sol-Gel method of first acidic and then alkaline can greatly shorten the gelling time.
