摘要： The invention describes a high porosity ceramic article and method of manufacturing the same and intermediate dried honeycomb green body articles. The article may have a total porosity of at least about fifty-five percent, above sixty percent, or even above sixty-five percent. The method of manufacture includes mixing a ceramic-forming powder, an organic pore former, water, and a crosslinker. Drying causes a condensation reaction between the pore former and the crosslinker thereby forming a network within the green body that strengthens the green body and reduces cracking. The pore former may include starch or an activated cellulose compounds. Secondary pore forming agents, such as graphite may also be included.

摘要： Disclosed are ceramic articles, which in one aspect are composed predominately of a cordierite having a composition close to that of Mg2Al4Si5O18. The ceramic articles possess a microstructure characterized by a unique combination of relatively high porosity and relatively narrow pore size distribution, both as measured by mercury porosimetry, that render the ceramic structure useful for ceramic filter applications requiring high thermal durability and high filtration efficiency coupled with low pressure drop along the length of the filter. Such ceramic bodies are particularly well suited for filtration applications, such as diesel exhaust filters or DPFs. Also disclosed are methods for the manufacture of the ceramic articles described herein.

摘要： Porous ceramic honeycomb articles for use as particulate filters and processes for making the same are described herein. The porous ceramic honeycomb articles include a fired cordierite body. The fired cordierite body has a microcrack parameter (Nb3) of about 0.05 to about 0.25 prior to exposure to a microcracking condition. After exposure to the microcracking condition, the fired cordierite body has a microcrack parameter (Nb3) at least 20% greater than the microcrack parameter prior to exposure to the microcracking condition. The fired cordierite body has a coefficient of thermal expansion (CTE) of about 7.0×10−7/° C. to about 15.0×10−7/° C. over from about 25° C. to about 800° C. prior to exposure to the microcracking condition and a coefficient of thermal expansion of about 1.0×10−7/° C. to about 10.0×10−7/° C. over from about 25° C. to about 800° C. after exposure to the microcracking condition. The microcrack parameter may include a thermal cycle or a chemical treatment.
