METHOD OF PRODUCING A DIE FOR EXTRUDING A CERAMIC BATCH INTO A HONEYCOMB STRUCTURAL BODY AND A DIE PRODUCED BY SUCH METHOD |
| 摘要 |
An extrusion die having lattice-like slits (2 min ) of very small width (i min ) can be easily obtained by plating a metal film (4) on the surface of slits (2) in the matrix (1) of the die. A honeycomb structural body produced by the use of the extrusion die has a very high cell density and a very large surface area, and is suitable as a catalyst carrier for the purification of exhaust gas of automobile. |
