PROBLEM TO BE SOLVED: To provide a method for manufacturing an inorganic molding at a low manufacturing cost by enhancing an efficiency of a manufacturing process and a strength by shortening a heat curing time. SOLUTION: The method for manufacturing the inorganic molding comprises a step of obtaining a material for the inorganic molding containing inorganic slurry which contains a hydrogen phosphate metallic salt and an inorganic reinforcing material, and a heating and pressurizing step capable of obtaining the inorganic molding by heat curing the material while pressure molding the material between molds for pressure molding. In this method, the heating and pressurizing step repeats pressurizing and interrupting of the pressurizing by opening and closing the mold heated by external heating. Electromagnetic heating of oscillating an electromagnetic wave between the molds is synchronize at least with part of repeating of the opening/closing, and at the pressurizing time the mold is electromagnetic-wave-heated and at the interrupting time of the heating the electromagnetic wave heating is interrupted. |
