To obtain a large-sized ceramic molding free from cracks and warpage by immersing a hydrogel-contg. ceramic molding in a solvent having a great affinity for water and having a lower b.p. and a smaller surface tension than water, carrying out solvent displacement and drying the molding.

A slurry contg. a ceramic powder, a gelling component and water is cast in a mold and converted into a hydrogel to form a gelled molding. This molding is immersed in a solvent having a great affinity for water and having a lower b.p. and a smaller surface tension than water, e.g. ethanol having 78.3°C b.p. or acetone having 56.3°C b.p., solvent displacement is carried out optionally under shaking and then the molding is dried to obtain a ceramic molding. The ceramic is, e.g. alumina, zirconia, silicon nitride, silicon carbide or sialon. The gelling component is, e.g. a gel such as methylcellulose, gelatin or starch or a water-soluble polymer of acrylamide and N,N'- methylenebisacrylamide.
