A honeycomb structure body which has a number of passagesnpartitioned with partition walls and penetrating along thenaxial direction. A porous honeycomb structure body whichncontains refractory grains as filler, one or more elementsnselected from the group consisting of the rare earth elements,nalkaline earth elements, Al, and Si, and the crystalncontaining one or more kinds of these elements. The presentnhoneycomb structure body contains refractory grains such asnsilicon carbide grains and the like, but it can be producednat a relatively low firing temperature at a low price, itnis sufficiently porous and high in specific surface area,nand it can be used as a filter for purifying automobile exhaustngas, a catalyst carrier, and the like under the high SVnconditions. |
