HONEYCOMB STRUCTURE AND METHOD FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2005/108328

Kind Code:

A1

Abstract:

A flat honeycomb structure exhibiting sufficient resistance against physical impact in which a sealing material layer is insusceptible to damage at the time of temperature rise and bonding strength can be maintained. The honeycomb structure has honeycomb units principally made of porous ceramic and having a large number of through holes arranged in the longitudinal direction and separated by partitions and a sealing material layer provided at the outer peripheral part of a plurality of flat ceramic blocks bonded through sealing material layers. The honeycomb structure is characterized in that the pattern of the sealing material layer between the honeycomb units in the cross-section perpendicular to the longitudinal direction is formed obliquely to the major axis of a shape forming the outline of the cross-section.
