Abstract
The structure of silica aerogel was studied by transmission electron microscopy. The aerogel network consists of particles about 10.0 nm in diameter. The chemical composition of these aggregates was found to be a pure stoichiometric SiO2 by both ESCA and Auger spectroscopy. These SiO2 groups appear to form a random network within each particle. The details of this arrangement have yet to be determined, because in this preliminary study, silica aerogel was found to transform after exposure to the intense electron beam.
