Abstract: Methods of manufacturing a ceramic honeycomb body having a honeycomb structure with a matrix of intersecting walls, and a skin disposed on an outer peripheral portion of the matrix where the skin has a first average porosity and the interior portion of the matrix has a second average porosity that is greater than the first average porosity. The methods include coating at least the skin with a fluid formulation containing a sintering aid and subsequently firing the honeycomb structure. In certain embodiments, a glass layer is formed in the skin or in regions of the walls directly adjacent to the skin. In certain embodiments, the coating is applied to a green honeycomb structure, and in other embodiments the coating is applied to a ceramic honeycomb structure. Other honeycomb bodies and methods are described.

Abstract: Aluminum titanate-containing particles made up of a conglomerate of multiple partial grains. The aluminum titanate-containing particles are formed by breaking apart ceramic bodies along cracks, which are formed predominantly through the grains, rather than between the grains. Batch mixtures forming the aluminum titanate-containing particles, as well as batch mixtures utilizing the aluminum titanate particles are disclosed. Green bodies, such as green honeycomb bodies having peak intensity ratios (PIRs) in an axial direction of less than or equal to 0.50, ceramic honeycomb bodies, methods of manufacturing green honeycomb bodies, and ceramic honeycomb bodies are provided, as are other aspects.
