ABSTRACT:
Only those dielectrics which have a correspondingly low sintering temperature are suitable for the production of ceramic multi-layer capacitors having intermediate electrodes consisting of non-noble metals, such as nickel and cobalt. Suitable are ceramic masses comprising alkaline earth zirconates, wherein up to 10 mole % of the zirconium may have been replaced by titanium; iron or nickel or manganese being added as doping agents to the stoichiometrical perowskite basic compound having a composition of alkaline earth metal (Zr.sub.1-x Ti.sub.x)O.sub.3 where O<x.ltoreq.0.07 and the whole assembly being sintered in a reducing atmosphere.
