Abstract: Ceramic moldings, in particular those having geometrically complicated shapes, are produced by a process in which a ceramic powder is mixed with a molding additive and the mixture is injected into a mold. In order to improve the mechanical properties of the molding, a solution of a high molecular weight polymer in a solvent is used as the molding additive. The mixture is injected at a temperature below the boiling point of the solvent and under from 100 to 1,500 bar into a porous, gas-permeable mold which is at a temperature above the boiling point of the solvent, the injection pressure being maintained until gas no longer escapes from the molding material or the mold.
