Shear binder agglomerates enabling high porosity in ceramic honeycomb bodies
A ceramic precursor mixtures for extrusion and firing into porous ceramics. The ceramic precursor mixtures include ceramic beads and green inorganic shear binder agglomerates. The green inorganic shear binder agglomerates can include inorganic filler particles and a polymeric binder. The green inorganic shear binder agglomerates can deform under an applied shear stress during mixing and/or extrusion such that they are smeared into a plurality of interbead gaps between adjacent ceramic beads or pore former particles. During firing, the smeared green inorganic shear binder agglomerates can sinter and react to form ribbons extending between, and interconnecting adjacent ceramic beads.
