Abstract: Batch compositions containing pre-reacted inorganic spheroidal particles, small amount of fine inorganic particles (“fines”), and an extremely large amount of liquid vehicle. The batch compositions contain pre-reacted inorganic particles having a particle size distribution with 20 μm≤D50≤100 μm, D90≤100 μm, and D5≥10 μm; less than 20 wt % of fine inorganic particles (fines) whose particle distribution(s) have a median diameter of less than 5 μm; and a liquid vehicle in a weight percent (LV %≥28%) by super-addition to all inorganic particles in the batch composition. Fast extruding batch compositions having extremely high Tau Y/Beta ratios are provided. Green bodies, such as green honeycomb bodies and methods of manufacturing green honeycomb bodies are provided, as are other aspects.

Abstract: A ceramic honeycomb body exhibiting a primary phase of aluminum titanate solid solution with a pseudobrookite structure, and a secondary phase of cordierite. The ceramic honeycomb body contains the aluminum titanate solid solution in an amount greater than or equal to 50 wt. % and cordierite in an amount greater than or equal to 20 wt. %. Low anisotropy is demonstrated by the primary phase of aluminum titanate solid solution by comprising an AT tangential/axial i-ratio≤1.35. Batch mixtures including spherical alumina and methods of manufacturing ceramic honeycomb bodies using the batch mixtures with spherical alumina are provided, as are other aspects.

Abstract: The disclosure relates to methods for making a ceramic or glass-ceramic, the methods comprising spray-drying a mixture comprising batch materials to form agglomerated particles; bringing the agglomerated particles into contact with a plasma for a residence time sufficient to form fused particles; and annealing the fused particles at a temperature and for a time sufficient to form ceramic or glass-ceramic particles. Fused glass particles, ceramic or glass-ceramic particles, and ceramic or glass-ceramic articles, such as ceramic honeycombs, made by these methods are also disclosed herein.
