Abstract: Methods of manufacturing honeycomb-structure-forming extrusion dies having a number of slots for use in producing extruded articles having complex honeycomb patterns and extrusion dies for use in the manufacture of extruded honeycomb bodies. The method includes inserting a die insert having a runner and a number of teeth into a slot of an extrusion die such that each of the teeth blocks at least a portion of the slot of the extrusion die. The method further includes separating the runner from the teeth so that the teeth remain within the slot of the extrusion die.

Abstract: A particulate filter having a honeycomb structure of a matrix of interconnected porous walls including inlet cells and outlet cells defining a plurality of inlet channels and outlet channels, respectively, wherein at least a portion of the outlet cells are larger than any of the inlet cells, and a cross-sectional shape of at least some of the outlet channels is rectangular. Honeycomb extrusion dies, honeycomb bodies, honeycomb structures, and methods of manufacture are described, as are other aspects.

Abstract: A method of manufacturing a ceramic honeycomb structure by mixing a ceramic precursor batch composition having a median particle diameter less than or equal to about 10 μm and at least one starch-based pore former having a median particle diameter greater than or equal to about 10 μm. The method also includes forming a mixture of ceramic precursor batch composition and a starch-based pore former into a green ceramic structure having a web structure, and firing the green ceramic structure to yield a ceramic honeycomb structure.
