<p>A honeycomb structure constructed of a cell partition (ribs) forming a composite of a plurality of cells adjoining each other, and a honeycomb outer wall enclosing and holding the outermost cells positioned on the periphery of the cell composite. The cell partition and the honeycomb outer wall are formed of a binding structure containing silicon carbide (SiC) as an aggregate and cordierite as a binder. The content ratio (volume %) of the silicon carbide (SiC) forming the binding structure to the total amount of the cordierite and the silicon carbide (SiC) is 40 to 90 %. This honeycomb structure exceeds a predetermined criterion required in any of thermal conductivity, chemical durability, low thermal expansion and mechanical strength and can be manufactured at a low cost, so that it can be preferably applied to a filter or catalyst carrier for cleaning the exhaust gases of an automobile.</p> |
