Abstract
The scanning transmission X-ray microscope at the Daresbury Laboratory has been used to form direct high-resolution images of gels prepared from aged silica sols at different pH values. The pH plays an importan t role in the determination of both the gelation rate and the microstr uctures observed in the aggregates of the silica gel. The fractal dime nsion of the structures can be used to study differences between the r esulting aggregates.
