A process for producing a non-dense sintered ceramic molded body having at least two layers, wherein a first powdery ceramic material forming a layer is contacted with at least a second powdery material forming at least a second layer； said first powdery material has a presintering temperature T1 that is higher than the presintering temperature Ts of said at least second powdery ceramic material； the course of a curve of shrinkage S1 of said at least first powdery ceramic material differs from the course of a curve of shrinkage S2 of said at least second powdery material, wherein curve of shrinkage S1 is shifted towards higher temperatures as compared to curve of shrinkage S2； and the layers are subjected to a common temperature treatment at a presintering temperature Ts that is lower than the presintering temperature T1 and at least equal to T3 to cause sintering that remains in a stage of sintering that has not proceeded to the theoretical density； wherein the curve of shrinkage S1 is modified by admixing at least one component having a curve of shrinkage S3 which material is compatible with said powdery ceramic material into said first powdery ceramic material, i. e. has a grain size smaller than the first powdery ceramic material, to equalize the curves of shrinkage S1 and S2 in the region of the presintering temperature Ts.L'invention porte sur un procédé pour la production d'un corps moulé en céramique fritté non dense ayant au moins deux couches, au moins une première matière céramique pulvérulente formant une couche étant mise en contact avec au moins une seconde matière pulvérulente formant au moins une seconde couche ； ladite première matière pulvérulente ayant une température de préfrittage T1 qui est supérieure à la température de préfrittage Ts de ladite ou desdites secondes matières céramiques pulvérulentes ； la ligne d'une courbe de retrait S1 de ladite ou desdites premières matières céramiques pulvérulentes différant de la ligne d'une courbe de retra
