<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a ceramic molding by which the molding is manufactured in a short period of time, working property is improved, consumption of energy is lowered and environmental preservation is improved. <P>SOLUTION: This method for manufacturing the ceramic molding includes a loading process for loading a powdery sintering material M composed of a metal oxide held between a pair of counter electrodes 50 (51, 52) into the inside of a cylindrical mold 60, a conductive layer forming process for forming a conductive layer due to a decrease in oxygen on the outer surface of the powdery sintering material M by heating the mold 60 by a mold heating member 80 in a state that the inside of the mold 60 is in a pressure reduced atmosphere, and a sintering process for sintering the powdery sintering material M having the conductive layer by heating the powdery sintering material M to a sintering temperature by the supply of current between the counter electrodes at least after the conductive layer forming process and pressing the counter electrodes 50 in a direction to be close to each other in or after the conductive layer forming process. <P>COPYRIGHT: (C)2004,JPO |
