摘要:
A honeycomb structure 100 has a plurality of flow paths 110a and 110b which are partitioned by partition walls 120 and are substantially parallel to each other; and one end of the flow path 110a is plugged by a plugging part 130 at one end surface 100a of the honeycomb structure 100, and one end of the flow path 110b is plugged by a plugging part 130 at the other end surface 100b of the honeycomb structure 100, wherein, in an image of the partition walls 120 obtained by X-ray CT measurement, when the number of communicating holes detected when resolution of the image is 1.5 μm/pixel is defined as X, and the number of communicating holes detected when resolution of the image is 2.5 μam/pixel is defined as Y, Y/X is 0.58 or more.
摘要:
A method of manufacturing a honeycomb structure comprises a step of forming a molded article by molding a raw material containing a ceramic powder and a pore-forming agent; and a step of manufacturing a honeycomb structure by sintering the molded article, wherein the pore-forming agent is powder formed of a material that disappears at a sintering temperature or less where the molded article is sintered, the powder is obtained by mixing a small particle size powder and a large particle size powder, a median particle size of which a ratio of a cumulative mass with respect to a total mass of the small particle size powder is 50% is 5 to 20 μm, a median particle size of which a ratio of a cumulative mass with respect to a total mass of the large particle size powder is 50% is 30 μm or more, and a ninety-percentage particle size of which a ratio of a cumulative mass with respect to a total mass of the large particle size powder is 90% is 80 μm or less.
