Abstract
There is disclosed a ceramic structure which comprises a material having a controlled pore distribution and including cordierite as the main crystal phase. In the pore distribution, the volume of pores having pore diameters smaller than 20 μm accounts for 15% or less of the total pore volume, and the volume of pores having pore diameters of 20 to 100 μm accounts for 70% or more of the total pore volume. This ceramic structure is suitable for realizing a ceramic catalyst body which has excellent purification efficiency, is reduced in pressure loss, and is mountable even in a limited space.
