A ceramic body exhibiting % P≥50%, df≤0.36, and a combined weight percentage of crystalline phases containing cordierite and indialite of at least 85 wt %, and up to 10 wt % of a crystalline pseudobrookite structured phase, such as armalcolite. The ceramic body contains, as expressed on an oxide basis, either: 1% wt % to 11% wt % titania and 89% wt % to 99% wt % MgO, AlO, and SiOthat have relative weight ratios of MgO:AlO:SiOwithin the field defined by 15.6:34.0:50.4, 12.6:34.0:53.4, 13.9:30.7:55.4, and 16.9:30.7:52.4, or 2.5% to 11% titania and 89% wt % to 97.5% wt % MgO, AlO, and SiOthat have relative weight ratios of MgO:AlO:SiOwithin the field defined by 15.6:34.0:50.4, 12.6:34.0:53.4, 12.0:35.7:52.3, and 15.0:35.7:49.3. Batch composition mixtures and methods of manufacturing ceramic bodies using the batch compositions are provided, as are other aspects.

Cordierite-indialite-pseudobrookite structured ceramic bodies, batch composition mixtures, and methods of manufacturing ceramic bodies therefrom

Disclosed is a honeycomb support structure comprising a honeycomb body and an outer layer or skin formed of a cement that includes an inorganic filler material having a first coefficient of thermal expansion from 25 C to 600 C and a crystalline inorganic fibrous material having a second coefficient of thermal expansion from 25 C to 600 C. Skin cement composition controls level of cement liquid/colloid components, for example water, colloidal silica, and methylcellulose migration into the substrate during the skin application process to form barrier to skin wetting and staining during the washcoating process.

Composite ceramic materials are disclosed herein which comprise two or more crystalline phases, wherein a first crystalline phase comprises a first refractory material having a first melting point, and a second crystalline phase comprises a second refractory material having a second melting point which is lower than the first melting point, and the second crystalline phase comprises large domain sizes of the second refractory material. Articles comprising such a composite ceramic material, such as honeycomb bodies, catalytic substrates, and particulate filters, are also disclosed herein, in addition to methods of manufacture thereof.

Composite ceramic materials, articles, and method of manufacture

Disclosed herein are methods for preparing a titanate compound powder comprising titanate compound particles having a controlled particle size and/or particle size distribution. The methods include mixing at least one first inorganic compound chosen from sources of a first metal or metal oxide, at least one second inorganic compound chosen from sources of titania, and at least one binder to form a mixture; calcining the mixture to form a polycrystalline material comprising a plurality of titanate compound grains and a plurality of microcracks; and breaking the polycrystalline material along at least a portion of the microcracks. Also disclosed are titanate compound powders having a controlled particle size distribution, ceramic batch compositions comprising the powders, and ceramic articles prepared from the batch compositions.

Ceramic powders with controlled size distribution

A composition for applying to a honeycomb body includes a refractory filler, an organic binder, an inorganic binder, and a liquid vehicle, wherein the refractory filler, the particle size distribution of the refractory filler, the organic binder, and the inorganic binder are selected such that, when the composition is applied to plug a plurality of channels of the honeycomb body, the plug depth variability is reduced.

A separator such as for an electrochemical double layer capacitor includes acicular inorganic particles that are dried to form a porous membrane. Example inorganic particles are calcium silicate particles. A deposition method implementing slurry that includes the acicular inorganic particles and a dispersing medium along with a binder material can be used to form the separator layer directly on electrode materials.

Disclosed is a honeycomb support structure comprising a honeycomb body and an outer layer or skin formed of a cement that includes an inorganic filler material having a first coefficient of thermal expansion from 25&#xb0; C. to 600&#xb0; C. and a crystalline inorganic fibrous material having a second coefficient of thermal expansion from 25&#xb0; C. to 600&#xb0; C.

Disclosed is a ceramic honeycomb structure comprising a honeycomb body and a multilayered outer layer formed of a thick core layer applied and rapidly dried and a thin clad layer dried more gently to form a crack free dual skin layer. The core layer may have properties that are closer to those of the ceramic honeycomb body in service than the clad layer that may provide a tough outer shell to withstand handling and assembly.
