A ceramic honeycomb body comprising a peripheral skin layer and a fiber extending around the outer periphery of a honeycomb core, the fiber embedded in the peripheral skin layer is described. A method of making a honeycomb body having a fiber extending around the outer periphery of a honeycomb core and embedded in the peripheral skin layer is also described.

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.

Embodiments are directed to glass-ceramic substrates with a III-V semiconductor layer, for example, a GaN layer that can be used in LED lighting devices. The glass-ceramics material is in the anorthite-rutile (CaAlSiO+TiO) family or in the cordierite-enstatite (SiO&#x2014;AlO&#x2014;MgO&#x2014;TiO) family.

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 Nb&#x2266;0.06 and an as-fired E/Eratio &#x2266;0.99. The article exhibits a coated microcrack parameter Nb&#x2266;0.14 and a coated E/Eratio &#x2266;1.06 after the porous ceramic honeycomb article has been washcoated and calcined at a temperature of 550&#xb0; C. After the article is exposed to a thermal treatment at a temperature &#x2267;800&#xb0; C. following washcoating and calcining, at least a first portion of the porous ceramic honeycomb article has a first treated microcrack parameter Nb&#x2267;0.18, and a first treated mean coefficient of thermal expansion of not more than 12&#xd7;10/&#xb0; C. over a temperature range of 25&#xb0; C. to 800&#xb0; C. Methods of forming the porous ceramic honeycomb article are also disclosed.

Low thermal expansion aluminum titanate zirconium tin titanate ceramics

Porous spodumene-cordierite honeycomb bodies of high strength but low volumetric density, useful for the manufacture of close-coupled engine exhaust converters, gasoline engine particulate exhaust filters, and NOx integrated engine exhaust filters, are provided through the reactive sintering of batches comprising sources of magnesia, alumina and silica together with a lithia source, such as a spodumene or petalite ore.

Beta-spodumene-cordierite composition, article, and method

The present invention describes a high porosity (% P&#x2267;45%), refractory, ceramic article comprising a cordierite ceramic phase and at least about 0.1 wt. % of a rare earth oxide, such as yttrium oxide or lanthanum oxide. When compared to typical high-porosity cordierite articles, the articles of the present invention may exhibit relatively high strength, relatively low microcracking, relatively high strain tolerance (MOR/E), and/or relatively high thermal shock resistance (TSP).
