PRODUCTION METHOD OF ORIENTED CERAMICS SINTERED COMPACT
PROBLEM TO BE SOLVED: To produce an oriented ceramics sintered compact having a high degree of orientation by using a magnetic field orientation.SOLUTION: A production method of an oriented ceramics sintered compact is provided that comprises the steps of: pouring a slurry containing tubular grains into a container and applying a magnetic field of 0.1 T or larger to the slurry to cause the tubular grains in the slurry to orient in the direction of the magnetic field; removing and/or solidifying a solvent to prepare a compact in which the tubular grains are oriented in the direction of the magnetic field; and sintering the compact to prepare an oriented ceramics sintered compact in which at least a part of sintered particles are oriented in the direction of the magnetic field.SELECTED DRAWING: None
【課題】磁場配向を用いて、より配向度の高い配向性のセラミックス焼結体を製造する。【解決手段】板状粒子を含むスラリーを容器内に流し込み、０．１Ｔ以上の磁場を印加して、スラリー中の板状粒子を磁場の方向に配向させる工程と、溶媒を除去及び／又は固化させて、板状粒子が磁場方向に配向した成形体を作製する工程と、成形体を焼結させて、焼結粒子の少なくとも一部が磁場方向に配向した配向性セラミックス焼結体を作製する工程とを含む、配向性セラミックス焼結体の製造方法。【選択図】なし
