Beschreibung
Zusammenfassung:	An electrically insulating supporting structure which may be mechanically stressed in all directions is capable of metallic bonding to electrically separated electroconductive components. As electrically insulating material a three-dimensionally compressed ceramic material, i.e. a ceramic material compressed almost from all sides, is used. The ceramic material is arranged between a first and a second metallic structure. Both structures are shaped so as to exercise a pressure on the ceramic material from almost all sides, without touching each other, however. The use of such supporting structures is particularly favourable in electrically heatable honeycomb bodies, in particular for catalytic converters in motor vehicles. The required insulating gaps (5, 6, 7) may be stabilized by electrically insulating but metallically bondable structures (41, 42; 51, 52; 61, 62). Thermal expansions and mechanical vibrations are thus better mastered and the service life of such a catalytic converter is increased.
