Abstract

The invention relates to a honeycomb (10) for a catalyst or a particle filter, which is produced by extruding a ceramic composition in such a way that the extrusion product has a central lattice structure (12) which is surrounded by a solid casing (14) with an external surface (16). After the sintering, at least one portion of the external surface (16) of the casing (14) is removed in such a manner that the end product has a desired external shape. It is proposed that the external surface (16) of the casing (14) be provided with a structuring (22) during the extrusion.
