Method for forming porous ceramic materials |
摘要 |
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 unsubstituted 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.
