| Abstract: | The changes in the Raman spectra of the silica sol-gels have been examined as a function of time. The increase of pressure from 1 bar to 3.5 kbar decreased the gelation time from 168 h down to 6 h. The bands associated with the SiO2 vibrations grow continuously with time indicating the continuous growth of network particles even after the gel had been formed. |
