  • Publication number: 20200299196
    Abstract: A method of making a porous cordierite ceramic article using chlorite raw material is described herein. The method includes mixing materials to form a cordierite-forming mixture. The cordierite-forming mixture includes a chlorite raw material in an amount of about 5% to about 60% by weight and a platy aluminum silicate raw material in an amount of 0% to about 30% by weight of the total inorganic content of the cordierite-forming mixture. The cordierite-forming mixture is then formed into a green body and fired to form the porous cordierite ceramic article. In some cases, the porous cordierite ceramic article exhibits a low coefficient of thermal expansion (CTE), which provides the article with high thermal shock resistance.

  • Patent number: 9409826
    Abstract: A porous ceramic honeycomb article includes a primary cordierite phase and an intercrystalline glass phase. In an as-fired condition, the porous ceramic honeycomb article exhibits microcrack parameter Nb3?0.06 and an as-fired E500° C./E25° C. ratio ?0.99. The article exhibits a coated microcrack parameter Nb3?0.14 and a coated E500° C./E25° C. ratio ?1.06 after the porous ceramic honeycomb article has been washcoated and calcined at a temperature of 550° C. After the article is exposed to a thermal treatment at a temperature ?800° C. following washcoating and calcining, at least a first portion of the porous ceramic honeycomb article has a first treated microcrack parameter Nb3?0.18, and a first treated mean coefficient of thermal expansion of not more than 12×10?7/° C. over a temperature range of 25° C. to 800° C. Methods of forming the porous ceramic honeycomb article are also disclosed.
