    摘要： Various embodiments provide methods of making ceramic articles and cold-set plugs for ceramic honeycomb bodies. The methods of making ceramic articles include providing a ceramic honeycomb body and applying an aqueous composition to the ceramic honeycomb body to form a cold-set plug. The aqueous composition includes a refractory filler, an inorganic binder, and an organic binder. The refractory filler includes particles having a d50 ranging from about 10 μm to about 40 μm, a d10 greater than about 2 μm, and a d90 less than about 110 μm. Embodiments also provide methods of making the cold-set plug that include preparing the aqueous composition and forming the cold-set plug by applying the composition to the ceramic honeycomb body.

    摘要： Disclosed are ceramic honeycomb articles, which are composed predominately of a crystalline phase cordierite composition. The ceramic honeycomb articles possess a microstructure characterized by a unique combination of relatively high porosity between 42% and 56%, and relatively narrow pore size distribution wherein less than 15% of the total porosity has a pore diameter less than 10 μm, less than 20% of the total porosity has a pore diameter greater than 30 μm, and dbreadth≦1.50 wherein dbreadth=(d90−d10)/d50. The articles exhibits high thermal durability and high filtration efficiency coupled with low pressure drop across the filter. Such ceramic articles are particularly well suited for filtration applications, such as diesel exhaust filters or DPFs. Also disclosed is a method for manufacturing the ceramic article wherein the pore former is preferably potato starch having a median particle diameter greater than 40 μm.

    摘要： Disclosed are porous ceramic honeycomb articles, such as filters, which are composed predominately of a cordierite composition. The ceramic honeycomb articles possess a porous microstructure characterized by a unique combination of relatively high porosity (>45%), and moderately narrow pore size distribution wherein greater than 15% and less than 38% of the total porosity exhibits a pore diameter less than 10 μm, and low CTE wherein CTE≦6.0×10−7/° C. (from 23° C. to 800° C.). The articles exhibit high thermal durability and high filtration efficiency coupled with low pressure drop. Such ceramic articles are particularly well suited for use in filtration applications, such as in diesel exhaust filters. Also disclosed are methods for manufacturing the porous ceramic honeycomb article.
