It is to provide a honeycomb structural body having an excellent durability, which is large in the catching amount of particulates per unit volume and does not cause uneven accumulation of ash and occurrence of cracks or the like even in use for a long period of time, and there is proposed a honeycomb structural body obtained by assembling one or plural porous ceramic members in which two kinds of through-holes consisting of a group of large volume through-holes and a group of small volume through-holes are arranged side by side in the longitudinal direction through partitions and either one ends of these through-holes are plugged, wherein the ceramic member is made of silicon-ceramic composite material consisting of ceramic and silicon.
A honeycomb structural body obtained by assembling one or plural pillar-shaped porous ceramic members, each being made by arranging a plurality of through-holes side by side in a longitudinal direction through partitions and plugging either one ends of these through-holes, characterized in that an opening area at one end face of the honeycomb structural body is different from an opening area at the other end face thereof, and the ceramic member is made of silicon-ceramic composite material consisting of ceramic and silicon.
A honeycomb structural body obtained by assembling one or plural pillar-shaped porous ceramic members, each being made by arranging a plurality of through-holes for the formation of cells side by side in a longitudinal direction through partitions and plugging either one end of these through-holes, characterized in that the porous ceramic member is made by combining a group of large volume through-holes plugged so as to make relatively large a sum of opening areas at one end surfaces in a section perpendicular to the longitudinal direction, and a group of small volume through-holes plugged so as to make relatively small a sum of opening areas at one end small in the other section, and the ceramic member is made of silicon-ceramic composite material consisting of ceramic and silicon.
