NON-OXIDE INORGANIC PORE-FORMERS FOR CORDIERITE CERAMIC ARTICLES
Cordierite-forming batch mixtures including one or more non-oxide inorganic source materials or materials as pore-formers are provided. Non-oxide inorganic materials, such a non-oxide silicon material that includes at least one of silicon carbide, silicon, or silicon nitride, may be added to cordierite-forming batch mixtures as at least a partial replacement for conventional inorganic pore-formers. Non-oxide inorganic pore-formers may provide an increase in pore volume while having a reduced coefficient of thermal expansion impact as compared with conventional pore-formers. Cordierite-forming mixtures as disclosed herein may additionally include rare-earth catalysts and alkaline-earth materials that may enhance the pore-forming effect of non-oxide inorganic pore-formers without significant exothermic reactions or the production of emissions that may require additional processing treatments.
