Abstract
This invention relates to the preparation of silica-containing particulate materials and monolithic structures exhibiting high porosity with exceptionally uniform pore size. The bodies are produced through gelation of aqueous alkali metal silicate and/or colloidal silica solutions, optionally contaiing dispersed particulate phases, with organic reagents followed by a leaching step. Uniformity of pore size is achieved through careful control of such variables as the ratio of alkali metal silicate to colloidal silica solutions, the concentration of silica, the amount of dispersed phase employed, and the like.
