Abstract

The evolution of the periodic structure, the strengthening of the Si-O bond and the formation of the 3-fold and 4-fold rings of Si-O were observed in SiO2 gels, which were prepared from alkoxide solutions, with heating but without catalysts. The content of water in the alkoxide solution related to the content of residual organic species, the behaviour of the Si-O bond with heating, and the range of the periodic structure in the gel.
