PROBLEM TO BE SOLVED: To provide a method capable of producing a solid powder molding in which the orientational properties of planar powder included in a powder raw material are improved, and characteristics caused by the planar powder are remarkably exhibited.SOLUTION: The method for producing a solid powder molding 21 includes a process where a planar powder-containing powder raw material 20 is subjected to pressure molding while applying ultrasonic vibration by pestles. The application of the ultrasonic vibration to the powder raw material 20 via the pestles is started till a time at which the density of the powder raw material 20 is less than that equal to tapping tampered density.COPYRIGHT: (C)2011,JPO&INPIT【課題】粉体原料中に含まれる板状粉体の配向性が向上し、該板状粉体に起因する特徴が顕著に発現する固形粉末成型体を製造し得る方法を提供すること。【解決手段】板状粉体を含有する粉体原料20を、杵によって超音波振動を印加しながら、加圧成型する工程を含む固形粉末成型体21の製造方法である。該杵を介した粉体原料20への超音波振動の印加を、該粉体原料20の密度がタッピング固め密度に相当する密度未満の間に開始する。【選択図】図3
