Zusammenfassung:A ceramic forming batch mixture including inorganic batch materials, such as sources of alumina, titania, and silica, a pore former combination including first and second pore formers with different compositions; an organic binder; and a solvent. Also disclosed is a method for producing a ceramic article involving mixing the inorganic batch materials with the pore former combination having first and second pore formers of different composition, adding an organic binder and a solvent, forming a green body; and firing the green body. A green body having a combination of first and second pore formers with different compositions is disclosed, as are several methods for firing to produce ceramic articles such as aluminum titanate.
