Abstract
It is unnecessary to add alcohol to a polymerizing silicon tetramethoxide-H2O sol-gel system as a co-solvent. The alcohol released during the reaction is sufficient to convert the initially biphasic system into a homogeneous one, resulting in the usual highly transparent, porous xerogel. We suggest that the alcohol-free sol-gel system may replace in many cases the traditional H2O-alcohol-alkoxide system.
