摘要： PROBLEM TO BE SOLVED: To provide a honeycomb structure in which the thermal stress to be generated when a local temperature change is caused in the honeycomb structure can be relaxed, which does not crack, is excellent in strength and durability and strong against a thermal shock and vibration and on which a catalyst component can be dispersed highly. SOLUTION: The honeycomb structure is constituted so that a plurality of columnar honeycomb units, in each of which many cells are arranged in parallel in the longitudinal direction while separating the adjacent cells from each other by a cell wall, are bonded to one another while interposing a sealing material layer between the adjacent honeycomb units. The honeycomb unit contains inorganic particles, inorganic fibers and/or whiskers. The cross-sectional area of the honeycomb unit in the cross section perpendicular to the longitudinal direction thereof is 5-50 cm 2 . The honeycomb structure satisfies the relational expression: 0.01≤(the absolute value of (α L -α F ))/α F ≤1.0 (wherein α L is the coefficient of thermal expansion of the sealing material layer; α F is the coefficient of thermal expansion of the honeycomb unit).

摘要： PROBLEM TO BE SOLVED: To provide a honeycomb structure strong against thermal shock or vibration, having high strength and excellent durability, and highly dispersing a catalyst component. SOLUTION: This honeycomb structure has irregularities formed on its outer periphery, and comprises inorganic particles and inorganic fibers and/or whisker. A least square curve of a point on a contour of a section perpendicular to the longitudinal direction of the honeycomb is found. When defining the center of gravity as c1, a distance between a least concentric circumscription of the least square curve and the center of gravity c1 as D1, a distance between a maximum concentric inscribed curve of the least square curve and the center of gravity c1 as D2, and M1 as D1-D2, M1 is 0.3 mm or less. A least square curve of a point constituting the contour of a section perpendicular to the longitudinal direction of the honeycomb is found. When defining the center of gravity as c2, a distance between a least concentric circumscription of the least square curve having the center of gravity c2 and the center of gravity c2 as D3, a distance between a maximum concentric inscribed curve of the least square curve and the center of gravity c2 as D4, and M2 as D3-D4, M2 is in the range of 0.5≤M2≤7.0 mm.

摘要： PROBLEM TO BE SOLVED: To bring exhaust gas into thorough contact with catalyst ingredients so as to purify the gas efficiently. SOLUTION: A honeycomb structure contains at least ceramic particles and an inorganic binder, and its area in contact with exhaust gas is increased by making the wall supporting catalyst ingredients 0.25 mm or thinner so as to permit thorough contact of the gas with catalyst ingredients. The thorough contact of the gas with catalyst ingredients can be also realized by meeting the relation equation (1): Y≥250×X+22,500 (50≤X≤80) (wherein Y is the specific surface area per unit volume, m 2 /L, and X is the numerical aperture, %). The structure may be a honeycomb structure aggregate consisting of two or more above structures joined with a sealing material layer sealed on parts of the outer surface of the structures without through openings.
