Appl. No.:

7/801152

Inventors:

Garry J. Garvey - Dobbs Ferry NY
Paul A. Iacobucci - Patterson NY
John D. Nowak - Yonkers NY

Assignee:

Akzo N.V. - Arnhem

International Classification:

C01B 3312

US Classification:

264140

Abstract:

Particulate ceramic precursor gel compositions (e. g. , particulate silica gel) are formed by mechanically extruding a substantially monolithic, substantially undried ceramic precursor. gel through a screen using a mechanical force which is supplied substantially normal to the plane of the screen to directly form the particulate composition, collecting the extrudate in a substantially non-stacked configuration, and drying the extrudate, e. g. , in a dryer without imposition of strong vacuum when the extrudate is in substantially nonlayered configuration, to substantially maintain its particle morphology.
