Zusammenfassung:A process for preparing a cordierite filter article, including: selecting an extruded green body batch composition and accomplishing a first firing at selected first parameters to provide a first-fired article having first pore properties; and accomplishing a second firing at a selected second parameter to provide a second-fired article having thermo-mechanical properties and having second pore properties. Also disclosed are cordierite filter articles, including a matrix of walls, prepared by the disclosed process.
