Abstract:
1. A method for producing a ceramic article comprising a sintered phase cordierite composition, comprising the steps of: mixing a dispersible alumina source and a magnesium oxide source in a solvent to provide a slurry premix; substantially removing the solvent from the slurry premix to provide a first dry premix; mixing at least one silica source together with the first dry premix to provide a cordierite precursor batch composition; mixing the cordierite precursor batch composition together with a binder system to form a plasticized cordierite precursor composition; forming a green body from the plasticized cordierite precursor composition; and firing the green body for a period of time and at a temperature sufficient to provide a ceramic article comprising the sintered phase composition.
