Ceramic honeycomb structure and method for producing ceramic honeycomb structure
concave A ceramic honeycomb structure having porous cell walls defining large numbers of flow paths, the cell walls having porosity of 55-70%, an average pore diameter of 10-40 μm, a concave area ratio CR (projected area ratio of portions lower than an average surface determined from cell wall surfa...

| Zusammenfassung: | concave A ceramic honeycomb structure having porous cell walls defining large numbers of flow paths, the cell walls having porosity of 55-70%, an average pore diameter of 10-40 μm, a concave area ratio CR (projected area ratio of portions lower than an average surface determined from cell wall surface roughness by a least square method) of 0.32-0.6, and an average concave depth H(average depth of portions lower than the average surface) of 0.02-0.1 mm. |
