| Abstract: | Porous silica gel glass was prepared by sol-gel process from tetraethoxysilane (TEOS). The effects of process parameters (such as type of solvents, temperature, drying conditions) on pore size distribution were studied. With the increasing amount of water, the pore size dis-tribution of gel glass becomes narrow and shifts to larger side. While when the ratio of C2H5OH/TEOS increases, the gelation time also increases and the average pore size reduces. Gels drying at high temperature has high specific surface area and large pore volume. The structure changes with temperature were analyzed by means of DTA and XRD. |
