Abstract:
1. A method of making a shaped body having a silica content of at least 85 wt %, the method comprising the steps of a) forming a shaped body from a mixture obtained from at least one amorphous silica powder, at least one silica sol having a pH below 7, at least one polymeric organic extrusion, aid, optionally crystallites of a zeolite or zeolite-type material, and optionally supplemental liquid medium, wherein the silica sol contributes to an amount from about 4 wt % to about 40 wt % of the overall silica in the mixture used in step a) excluding the optional zeolite or zeolite-type material; and wherein the polymeric organic extrusion aid is used in an amount from about 0.5 to about 10 parts by weight per 100 parts by weight of the overall silica present in the mixture used in step a); b) drying the shaped body obtained in step a); and c) heating the shaped body to a temperature ranging from about 500° C. to about 800° C. to form a calcined shaped body.
