A review on the combination of fractal concepts with exptl. data obtained by non-invasive methods (NMR, SAXS, SANS, visible light scattering) for studying silica dispersions. Significant progress has been made in understanding elementary processes involved in the aggregation, gelation, and aging steps during the prepn. of porous silica. 29 Refs. [on SciFinder (R)
