Monodisperse silica spheres were prepared by hydrolysis and condensation of tetraethoxysilane (TEOS) in a mixture of water, ammonia and ethanol or acetone at 25℃. The spheres were studied with 13C CP-MAS NMR and their carbon contents were determined. It was found that TEOS was hydrolyzed completely during the sythesis process of monodisperse silica particles and that the carbon inside the silica is in the form of free solvent sheilded in the silica, this is, in accord with the mechanism of aggregation growth.
