Abstract
A method of producing a ceramic molding having a desired shape involves extruding a ceramic material that has been pressure-fed into a resistance pipe. By using a production apparatus including a screw type extruder and mold, connected to the distal end of the extruder through the resistance pipe, the ceramic material is pressure-fed from the extruder into the resistance pipe. The resistance pipe is heated or cooled at its periphery so as to control the shape of the ceramic molding extruded from the mold.
