Peroxide containing compounds as pore formers in the manufacture of ceramic articles

摘要

A method for manufacturing porous ceramic articles comprised of a primary sintered phase ceramic composition. The method includes the steps of providing a plasticized ceramic precursor batch composition including ceramic forming inorganic batch components; a liquid vehicle; an organic binder system; and a pore forming agent comprising at least one peroxide containing compound. An extruded green body is formed from the plasticized ceramic precursor batch composition and subsequently fired under conditions effective to convert the extruded green body into a ceramic article comprising a porous sintered phase composition. Also disclosed are ceramic article produced by the methods disclosed herein.
