HONEYCOMB STRUCTURE AND PROCESS FOR PRODUCING THE HONEYCOMB STRUCTURE

摘要

A honeycomb structure which, even when thermal cycling as in a regeneration treatment is repeated over long, is less apt to break between the adhesive layer and the sealing material layer. The honeycomb structure comprises: a ceramic block obtained by bundling, through an adhesive layer, two or more columnar honeycomb burning products in which many cells separated by a cell wall are arranged in the lengthwise direction; and a sealing material layer formed around the ceramic block. It is characterized in that the adhesive layer and the sealing material layer have been integrally formed and there is no boundary between the two.
