Patent ID: 8101270

Claim:
A bonding material for a honeycomb structure, comprising: inorganic particles, all of which are non-spherical and all of which have a D90/D10 from 10 to 500, a D10 of 100 μm or less and a D90 of 4 μm or more; and oxide fibers having an average length of 30 to 600 μm and an average diameter of 1 to 20 μm; wherein the D10 and D90 are the values of 10% diameter and 90% diameter from a smaller particle diameter side, respectively, in volume-based integrated fractions of a particle diameter distribution measurement by a laser diffraction/scattering method; and wherein an average long axis/short axis ratio of each of the inorganic particles is in a range of 1.1 to 4.0.
