PROBLEM TO BE SOLVED: To provide a method of producing a powder compact, that excels in mold releasability, suppresses product variance, and improves dimensional accuracy and increases productivity and, particularly is optimally applicable to a method of producing a compact for a turbine. SOLUTION: In the method of producing a powder compact, a powder compact is produced by casting a slurry containing ceramic and/or metallic powder, a dispersion medium, and a gelling agent and by solidifying it by gelling the slurry. After the slurry is cast in a mold 3 for a powder compacting and hardened, the hardened slurry is cooled with the mold in which the powder compact 1 is stored while it is hardened. Thus, by causing temperature difference in the mold 3 and the powder compact 1, mold releasing is performed. COPYRIGHT: (C)2011,JPO&INPIT
