METHOD OF PRODUCING TRANSPARENT CERAMIC FOR FARADAY ROTATOR
To provide a method of producing a transparent ceramic for a Faraday rotator composed of rare earth compound oxide, smaller in residual strain inside of a sintered compact than that obtained by dry molding represented by press molding, and excellent in transparency and extinction ratio performance.SOLUTION: A method of producing a transparent ceramic for a Faraday rotator composed of a sintered compact of cubic crystalline rare earth compound oxide includes a centrifugal molding process of encapsulating a slurry composed of a dispersoid containing a raw material powder for sintering, and a dispersant in a molding vessel, and separating into the dispersoid and the dispersant inside the molding vessel by centrifugal separation to form the dispersoid containing the raw material powder for sintering into a molded body having a predetermined shape.SELECTED DRAWING: Figure 1
【課題】プレス成形に代表される乾式成形よりも焼結体内部の残留歪みが小さく、透明性及び消光比性能の優れた希土類複合酸化物からなるファラデー回転子用透明セラミックスの製造方法を提供する。【解決手段】立方晶の希土類複合酸化物の焼結体からなるファラデー回転子用透明セラミックスの製造方法であって、焼結用原料粉末を含む分散質と分散媒とからなるスラリー又は泥漿を型容器に封入し、遠心分離により型容器内で分散質と分散媒とに分離させると共に焼結用原料粉末を含む分散質を所定形状の成形体とする遠心成形工程を有する。【選択図】図１
