METHOD FOR PRODUCING ORIENTED CERAMIC SINTERED COMPACT
PROBLEM TO BE SOLVED: To produce an oriented ceramic sintered compact oriented to a high degree even in a low magnetic field, using magnetic field orientation.SOLUTION: There is provided a method for producing an oriented ceramic sintered compact, comprising: a step where planar particle-containing raw material powder and graphene are prepared; a step where the treatment of covering at least a part of the surfaces of the planar particles with graphene is applied to the raw material powder to make the graphene-covered planar particle-containing treated powder; a step where the treated powder and a solvent are mixed to prepare slurry; a step where a magnetic field is applied to the slurry to orient the planar particles to a prescribed direction; a step where the solvent in the slurry is removed and/or solidified to make a molded body in which the planar particles are oriented to a prescribed direction; and a step where the molded body is fired to make an oriented ceramic sintered compact in which at least a part of the sintered particles is oriented.SELECTED DRAWING: None
【課題】磁場配向を用いて、低磁場でも高度に配向した配向性セラミックス焼結体を製造する。【解決手段】板状粒子を含む原料粉末と、グラフェンとを用意する工程と、板状粒子の表面の少なくとも一部をグラフェンで被覆する処理を原料粉末に施して、グラフェン被覆板状粒子を含有する処理粉末を作製する工程と、処理粉末と溶媒とを混合してスラリーを調製する工程と、スラリーに磁場を印加して板状粒子を所定の方向に配向させる工程と、スラリー中の溶媒を除去及び／又は固化させて、板状粒子が所定の方向に配向した成形体を作製する工程と、成形体を焼成して、焼結粒子の少なくとも一部が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
