A method and device for producing shaped ceramic bodies, particularly ceramic sheets or multilayer hybrids provided with printed circuit traces, switching elements and/or plated-through holes. The shaped ceramic bodies are initially present as green bodies and also contain organic auxiliary agents, for example as a binder. During sintering and/or removal of the binder from the shaped ceramic bodies, they are compressed between porous setter plates in whose pores a catalytically active substance is introduced, so that the gaseous, organic, bake-out products of the green bodies, these products developing during sintering and/or binder removal, are catalytically converted when escaping through the porous setter plates. The setter plates be provided with separating layers that likewise may contain the catalytically active substance. The method should provide a considerable time savings when sintering and/or removing binder from the shaped ceramic bodies.
