摘要：

This work deals with the synthesis of silica-iron oxide aerogels from gels obtained by hydrolysis and polycondensation of tetramethoxysilane and iron acetylacetonate sols in methyl alcohol. Aerogels with various iron contents were studied by DTA. TGA, X-ray and dilatometry. The sol to gel evolution was studied by UV-visible spectroscopy. Spectral evolution observed during gelation is related to the change of iron surroundings.
