Abstract
Small-angle X-ray scattering and (29Si—27Al) NMR were used to study the growth process and structure of sols and gels in the silicon-aluminium ester /H2O/i PrOH system. The structure of elementary particles is governed by a chemical growth process with the formation of Al-O-Al linkages, and the self-similar structure of the gel (fractal dimension of 1.8) results from a cluster-cluster growth processKeywords
