ABSTRACT:
A method of making a ceramic shaped article from an inorganic raw material powder by extrusion molding is disclosed. The method comprises the steps of kneading an inorganic raw material powder with a plasticizer to obtain a kneaded body which is then molded by extrusion into a fluid having a high humidity to obtain a ceramic shaped article having no deformation and strain. The plasticizer is selected from the group consisting of mono-liquid type resin which is a water insoluble synthetic resin dissolved in a water soluble solvent and a hydraulic setting resin mainly consisting of polyurethane isocyanate prepolymer.
