CERAMIC HONEYCOMB STRUCTURAL BODY
To provide a ceramic honeycomb structural body that achieves a lower pressure drop at an initial stage of PM collection (1 g/L), providing the PM collection rate that allows for effectively collecting nanosize PM, which significantly influences the number and amount of PM in exhaust, and preventing a pressure drop after the PM collection, and demonstrating improved thermal shock resistance.SOLUTION: The ceramic honeycomb structural body has a total pore volume of 0.54 to 0.62 cm3/g, the volume of pores of not smaller than 1 μm of 0.53 to 0.61 cm3/g, that of not smaller than 2 μm of 0.51 to 0.59 cm3/g, that of not smaller than 5 μm of 0.48 to 0.55 cm3/g, that of not smaller than 10 μm of 0.41 to 0.49 cm3/g, that of not smaller than 15 μm of 0.21 to 0.40 cm3/g, that of not smaller than 20 μm of 0.08 to 0.25 cm3/g, that of not smaller than 30 μm of 0.025 to 0.075 cm3/g, that of not smaller than 50 μm of 0.015 to 0.037 cm3/g, that of not smaller than 100 μm of 0.005 to 0.025 cm3/g, and that of not smaller than 200 μm of not more than 0.015 cm3/g.SELECTED DRAWING: Figure 1
