Honeycomb structural body and method of manufacturing the structural body

摘要

A honeycomb structure 1 having numerous through channels passing through along the X axis and being partitioned with porous partition walls 2 which is characterized in that: a total pore volume (D) cc/g in end portions of the partition walls 2 is smaller than the total pore volume in other portions of partition walls 2; and relationships between the total pore volume (D) cc/g in end portions and the partition wall thickness (B) mum and cell pitch (C) mm in other portions of partition walls are defined as; the total pore volume (D)<=the partition wall thickness (B)x0.004, and the total pore volume (D)<=(1/the cell pitch (C))x0.18; and a method of producing a honeycomb structure. There is provided with the honeycomb structures 1 having various cell structures and being reinforced at their end portions, with exhibiting satisfactory and practical erosion resistance.
