DESCRIPTION

A method for producing high surface area, thermally stable. Microporous porous ceramic materials involves replacing a portion of the silicon in a sol or gel comprising silica (silicon dioxide) with cations of another metal. The metal-substituted silica sols are dried and fired to yield porous ceramic materials. Similarly, metal-substituted gels are fired to yield porous ceramic materials. When compared with unsubstitued silica materials, the materials thus produced offer
advantageous benefits including improved stability in a basic environment, enhanced thermal stability, and advantageous surface properties such as intrinsic negative charge.
