Dried gels prepared by the sol-gel method from a mixture of tetramethoxysilane (TMOS) , water using a variety of solvents. The structure of dried gels was remarkably varied with the solvent used. The bulk density of dried gels decreased with decreasing vapor pressure of solvents except for 1, 4-dioxane. The bulk density of dried gel is closely related to the pore radius and pore volume. A dried gel with a small bulk density has a large pore radius and a large pore volume. Solvents with a long linear chain and a functional group which is exchangeable with a silanol group were effective to prepare the dried gel with small bulk density and a large pore radius.
