The substituted silicate sols thus prepared are then dried by, for example, placing the sols in plastic petri dishes in a desiccator with a drying reagent such as MgCl2 •6H2 O. Usually, the solvent in the sol evaporates in about 3 days, leaving behind a xerogel that may be sintered at temperatures between about 200� and 900� C. or higher, and preferably at about 500� C., to form a porous ceramic material in which a desired percentage of the silicon atoms are replaced.
