Abstract: A body is disclosed which is at least about 90% by weight cordierite, and has a coefficient of thermal expansion of less than about 16 x 10 / DEG C from about 25 DEG C to about 1000 DEG C. Also disclosed is a method of fabricating the body. Raw materials are selected to form a nominal composition consisting essentially of in percent by weight about 11.5 to about 16.5 MgO, about 33.0 to about 41.0 Al2O3, and about 46.5 to about 53 SiO2. The raw materials can be a combination of silica and magnesium aluminate spinel, a combination of silica, magnesium aluminate spinel, and a MgO yielding component, or a combination of silica, magnesium aluminate spinel, and a Al2O3 yielding component. The raw materials are provided absent of clay and talc. The raw materials are blended with an effective amount of vehicle and forming aids to impart plastic formability and green strength thereto form a plastic. The raw materials are formed into a green body which is dried and fired at a sufficient temperature for a sufficient time to form the cordierite body.

Abstract: A body is disclosed which is at least about 90% by weight cordierite, has a mean pore size of less than about 10.0 microns, and a coefficient of thermal expansion of no greater than about 9.0 x 10 / DEG C from about 25 DEG C to 1000 DEG C. Also disclosed is a method of fabricating the body. Raw materials are selected to form a composition consisting essentially of in percent by weight about 12 to 16 magnesium oxide, about 35 to 41 aluminum oxide, and about 43 to 53 silica. The raw materials are absent of clay and talc. The magnesium oxide is supplied by a magnesium oxide component having an average particle size of no greater than about 15.0 micrometers in diameter. The aluminum oxide is supplied by an aluminum oxide component having an average particle size of no greater than about 8.0 micrometers in diameter. The composition is capable of forming cordierite in the subsequent firing step. The raw materials are blended with an effective amount of vehicle and forming aids to impart plastic formability and green strength thereto and form a plastic mixture. The raw materials are formed into a green body which is dried and fired. The firing is done by heating to a first temperature of about 1000 DEG C to 1200 DEG C and thereafter raising the temperature at a rate of less than about 100 DEG C per hour to a second temperature sufficient to form cordierite, and maintaining the second temperature for a sufficient time to form the cordierite body.

Abstract: In one embodiment, a honeycomb structure formed from ceramic material, or ceramic honeycomb structure, includes at least one outer wall defining a perimeter of the honeycomb structure. A plurality of primary zone partitions and secondary zone partitions may extend in an axial direction of the honeycomb structure and across a width of the honeycomb structure. The primary zone partitions and the secondary zone partitions intersect with one another to divide a radial cross section of the honeycomb structure into a plurality of zones. The primary zone partitions and the secondary zone partitions may have a single-wall thickness with a maximum thickness Tzmax. Each zone may comprise a plurality of channel walls intersecting to subdivide the zone into a plurality of through channels extending in the axial direction of the honeycomb structure, the plurality of channel walls within each zone having a thickness of at least tc and TZmax>2tC.

Abstract: A binder system for use in the formation of ceramic or other powder-formed greenware including a binder, a solvent for the binder, a surfactant, and a component that is non-solvent with respect to the binder and solvent. The non-solvent component exhibits a lower viscosity than the solvent when containing the binder and includes a low molecular weight oil having a 90% recovered distillation temperature range of between about 220 to 400° C. Also disclosed is a process of forming and shaping plasticized powder mixtures and a process for forming ceramic articles utilizing the binder system.
