Abstract

A process for producing a composite, containing at least one shrinkage-matched ceramic layer, wherein a starting material for the ceramic layer(s) has shrinkage behavior on sintering which is matched to remaining layer(s), and which is selected such that the ceramic-forming constituent of the same contains at least one ceramic powder of a specific size, and which process entails joining the layers of the composite by sintering.
