摘要:
A honeycomb structure 1 comprising a honeycomb segment bonded body 10 having a number of honeycomb segments 2 integrated on each bonding planes via bonding material layers 9 has a structure so that a number of cells 5 providing fluid flow channels are disposed in parallel in the direction of center axis thereof. The honeycomb structure 1 is constructed so that the porosity of an outer portion of the bonding material layers 9 (an area from the interface with the honeycomb segment-bonding plane to a point apart from that interface by a distance equivalent to 20% of the entire layer thickness) is smaller than the porosity of a central portion located inward of the outer portion, and so that the bonding material layers 9 have a compression Young's modulus along the Z-axis of 5 to 100 MPa.

There is disclosed a honeycomb structure 1 which is made of a ceramic material and in which a plurality of honeycomb segments 12 having cell structures 5 and porous outer walls 7 on outer peripheries of the cell structures 5 are integrated by bonding the outer walls 7 to one another with a bonding material, each of the cell structures being provided with a plurality of cells 3 constituting fluid channels divided by porous partition walls 2, wherein the bonding material contains a bio-soluble fiber. The honeycomb structure 1 of the present invention has a performance equivalent to that of a honeycomb structure in which a heretofore used ceramic fiber is contained.

In a honeycomb structure 1 which is made of a ceramic and in which a plurality of honeycomb segments 12 having cell structures 5 and porous outer walls 7 on outer peripheries of the cell structures 5 are integrated by bonding these outer walls 7 to one another with a bonding material 8, each of the cell structures being provided with a plurality of cells 3 constituting fluid channels divided by porous partition walls 2, a base material constituting the honeycomb structure 1 has a thermal conductivity of 0.1 to 20 W/mK. Moreover, an outer periphery coating material constituting the outer peripheral wall of the honeycomb structure 1 has a porosity of 10 to 60%. Furthermore, the outer periphery coating material constituting the outer peripheral wall of the honeycomb structure 1 has a thermal conductivity of 0.01 to 0.5 W/mK.
