Abstract
A method for producing an aluminum-titanate-based ceramic honeycomb structure comprising blending TiOsource powder and AlOsource powder with a TiO/AlOmolar ratio of 45/55 to 55/45, and a sintering aid and/or a molding aid to prepare a moldable material, extrusion-molding the moldable material, and drying and sintering the resultant extrudate, the TiOsource powder having a particle size distribution (mass-based frequency distribution relative to [log(particle size)]), in which both the maximum frequency in a particle size range of 0.2-4 μm and the maximum frequency in a particle size range of 10-100 μm are larger than those in other ranges than the two particle size ranges.
