CERAMIC HONEYCOMB STRUCTURE |
| 摘要 |
<p>A ceramic honeycomb structure (1) constituted by cell walls (ribs) (2) forming a composite structure from a plurality of cells (3) being adjacent each other and a honeycomb outer wall (4) surrounding and holding the outermost peripheral cells located at the circumference of the composite structure; said composite structure satisfying the followings: the basic thickness of the cell walls (2) (the basic cell wall thickness) (Tc) is Tc </= 0.12 mm, the outer wall thickness (Ts) of the honeycomb structure is Ts >/= 0.05 mm, and the open frontal area (P) is P >/= 80%, and there is a relation shown by formula: 1.10 </= (Tr1 SIMILAR Tr3-20)/Tc </= 3.00 between the basic cell wall thickness (Tc) and each cell wall thickness (Tr1 SIMILAR Tr3-20) of cells existing between an outermost peripheral cell and any cell within a first end cell from a fifth cell to a twentieth cell extending inwardly, taking the outermost peripheral cell as a first staring cell. <IMAGE></p> |
