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.
