    New search for: AWATA HIDEAKI

    PROBLEM TO BE SOLVED: To provide a nitride sintered compact in which nitride crystal particles are oriented in a predetermined direction.SOLUTION: A production method of a nitride sintered compact includes: arranging a first powder including nitride crystal particles; preparing a second powder including oxygen by heating the first powder in an atmosphere having an oxygen partial pressure of 1×10Pa or higher and 1×10Pa or lower; forming a molding by molding the second powder in a magnetic field; and forming a nitride sintered compact by heating the molding in a reducing atmosphere.SELECTED DRAWING: Figure 1

    【課題】窒化物結晶粒子が所定方向に配向している、窒化物焼結体を提供すること。【解決手段】窒化物焼結体の製造方法は、窒化物結晶粒子を含む第１粉末を準備すること、酸素分圧が１×１０-5Ｐａ以上１×１０-1Ｐａ以下である雰囲気中で、該第１粉末を加熱することにより、酸素を含有する第２粉末を調製すること、磁場中で、該第２粉末を成形することにより、成形体を形成すること、および還元雰囲気中で、該成形体を加熱することにより、窒化物焼結体を形成すること、を含む。【選択図】図１
