CORDIERITE-CONTAINING CERAMIC BODIES, BATCH COMPOSITION MIXTURES, AND METHODS OF MANUFACTURING CORDIERITE-CONTAINING CERAMIC BODIES

Abstract:

A cordierite-containing ceramic body with % P.gtoreq.50%, df.ltoreq.0.50, and a combined weight percentage of crystalline phases containing cordierite and indialite of at least 85 wt %. The porous ceramic body contains, as expressed on a relative oxide weight percent basis in terms of MgO, Al.sub.2O.sub.3, and SiO.sub.2 that is within a field defined by (15.4, 34.1, and 50.5), (12.2, 34.1, and 53.7), (13.3, 31.2, and 55.5), and (16.6, 31.1, and 52.3). Batch composition mixtures and methods of manufacturing a porous ceramic body using the batch compositions are provided, as are other aspects.
