    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: A ceramic precursor batch composition comprising inorganic ceramic-forming ingredients, a binder, an aqueous solvent and a heteroatom polyol agent. The heteroatom polyol agent can be represented by X(R) where X is at least one of S, N, and P, and R is at least two of CH3, CH2CH2OH, CH2CH2CH2OH, CH2(CHOH)CH3, C(CH2OH)1-3, CH2OH, CH(CH2OH)CHOH, C(O)(CHOH)1-4CH2OH, and CH2CH2CH2OCH3. The presence of the heteroatom polyol agent provides a composition with a lower viscosity and/or a greater batch stiffening temperature (Tonset) allowing for increased rates of extrusion. Methods for producing a ceramic honeycomb body using this ceramic precursor batch composition are also provided.

    Abstract: A method for inhibiting oxygen and moisture degradation of a device and the resulting device are described herein. To inhibit the oxygen and moisture degradation of the device, a low liquidus temperature (LLT) material which typically has a low low liquidus temperature (or in specific embodiments a low glass transition temperature) is used to form a barrier layer on the device. The LLT material can be, for example, tin fluorophosphate glass, chalcogenide glass, tellurite glass and borate glass. The LLT material can be deposited onto the device by, for example, sputtering, evaporation, laser-ablation, spraying, pouring, frit-deposition, vapor-deposition, dip-coating, painting or rolling, spin-coating or any combination thereof. Defects in the LLT material from the deposition step can be removed by a consolidation step (heat treatment), to produce a pore-free, gas and moisture impenetrable protective coating on the device. Although many of the deposition methods are possible with common glasses (i.e. high melting temperature glasses like borate silicate, silica, etc.), the consolidation step is only practical with the LLT material where the consolidation temperature is sufficiently low so as to not damage the inner layers in the device.
