Abstract:
1. A method for producing an aluminum-titanate-based ceramic honeycomb structure comprising blending TiO 2 source powder and Al 2 O 3 source powder with a TiO 2 /Al 2 O 3 molar ratio of 45/55 to 55/45, and a sintering aid and/or a molding aid to prepare a moldable material, extrusion-molding said moldable material, and drying and sintering the resultant extrudate, said TiO 2 source powder having a particle size distribution, wherein the particle size distribution is a mass-based frequency distribution relative to [log(particle size)], in which both a maximum frequency in a particle size range of 0.2-4 μm and a maximum frequency in a particle size range of 10-100 μm are larger than a maximum frequency in a particle size range of more than 4 μm and less than 10 μm, a maximum frequency in a particle size range of less than 0.2 μm and a maximum frequency in a particle size range of more than 100 μm.
