| 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. | ||

| 主权项 | 1. A method for manufacturing a honeycomb structural body comprising: (i) providing a plurality of silicon carbide honeycomb segments each having a cell structure and at least one outer wall; (ii) subjecting said honeycomb segments to an oxidizing thermal treatment forming a surface layer of silicon oxides on said at least one outer wall; and (iii) bonding said plurality of oxidized honeycomb segments so as to form said honeycomb structural body in substantial absence of organic binders, with interposition of a sealing material consisting of a mixture of one or more silicon carbide powders, one or more ceramic fibers, and one or more inorganic binders, wherein no organic binder is added to the sealing material and wherein the one or more ceramic fibers have a length of about 0.5 to about 50 mm. | ||
