| 摘要 |
A method for producing an aluminum-titanate-based ceramic honeycomb structure comprising blending TiO2 source powder and Al2O3 source powder with a TiO2/Al2O3 molar 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 TiO2 source 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 0.2-4μm and the maximum frequency in a particle size range of 10-100μm are larger than those in other ranges than the two particle size ranges.
