HONEYCOMB STRUCTURAL BODY FOR EXHAUST GAS PURIFICATION |
摘要 |
A honeycomb structural body and a method for the manufacturing thereof. The manufacturing method includes (i) providing a plurality of silicon carbide honeycomb segments, each having a cell structure and at least one outer wall; (ii) subjecting the honeycomb segments to an oxidizing thermal treatment forming a surface layer of silicon oxides on the at least one outer wall; and (iii) bonding the plurality of oxidized honeycomb segments so as to form the honeycomb structural body in the substantial absence of organic binders with the interposition of a sealing material including a mixture of one or more silicon carbide powders, one or more ceramic fibers, and one or more inorganic binders. |
