| Abstract: | PEG was added into TEOS-Water-Ethanol-catalyst system. The effects of the PEG on SBET, particle radius distribution and pore structure in silica sol and gel were studied. From the changes of the particle sizes in' the sol, the model of the PEG behaviour in the sol-gel processes was described. |

| Keywords: | sol-gel pore structure particles distribution PEG SiO2 |
