Abstract: A honeycomb body having a porous ceramic honeycomb structure with a first end, a second end, and a plurality of walls having wall surfaces defining a plurality of inner channels. A highly porous layer is disposed on one or more of the wall surfaces of the honeycomb body. The highly porous layer has a porosity greater than 90%, and has an average thickness of greater than or equal to 0.5 μm and less than or equal to 10 μm. A method of making a honeycomb body includes depositing a layer precursor on a ceramic honeycomb body and binding the layer precursor to the ceramic honeycomb body to form the highly porous layer.

Abstract: A method for applying a surface treatment to a plugged honeycomb body comprising porous wall includes: mixing particles of an inorganic material with a liquid vehicle and a binder material to form a liquid-particulate-binder stream; mixing the liquid-particulate-binder stream with an atomizing gas, directing the liquid-particulate-binder stream into an atomizing nozzle thereby atomizing the particles into liquid-particulate-binder droplets comprised of the liquid vehicle, he binder material, and the particles; conveying the droplets toward the plugged honeycomb body by a gaseous carrier stream, wherein the gaseous carrier stream comprises a carrier gas and the atomizing gas; evaporating substantially all of the liquid vehicle from the droplets to form agglomerates comprised of the particles and the binder material; depositing the agglomerates onto the porous walls of the plugged honeycomb body; wherein the deposited agglomerates are disposed on, or in, or both on and in, the porous walls.

Abstract: Methods for applying a surface treatment to a plugged honeycomb body comprising porous wall includes: atomizing particles of an inorganic material into liquid-particulate-binder droplets comprised of an aqueous vehicle, a binder material, and the particles, evaporating substantially all of the aqueous vehicle from the droplets to form agglomerates comprised of the particles and the binder material, and depositing the agglomerates onto the porous walls of the plugged honeycomb body, wherein the agglomerates are disposed on, or in, or both on and in, the porous walls. Plugged honeycomb bodies comprising porous walls and inorganic material deposited thereon are also disclosed.

Abstract: A filtration article having a honeycomb filter body that includes a plurality of intersecting porous walls including surfaces that define a plurality of channels extending in a longitudinal direction from an inlet end to an outlet end. The plurality of channels includes inlet channels that are open at the inlet end and sealed at locations longitudinally spaced away from the inlet end, and outlet channels that are open at the outlet end and sealed at locations longitudinally spaced away from the outlet end. Inorganic deposits are disposed on, or in, or both on and in, at least some of the walls. The inorganic deposits are bound to each other, to the walls, or to both, by a silicon-containing precursor binder.
