本発明において最も重要な点は、特定の組成のNi−Zn−Cu−Coフェライトからなるフェライト焼結板又はフェライト焼結シートは、μ′が高く、μ″が低いという事実である。
Ni−Zn−Cu−Coフェライトの組成が、所定の組成になるように各酸化物原料を秤量し、ボールミルを用いて20時間湿式混合を行った後、混合スラリーを濾別・乾燥して原料混合粉末を得た。該原料混合粉末を730℃で3時間焼成して得られた仮焼成物をボールミルで粉砕し、本発明に係るNi−Zn−Cu−Coフェライト粉末を得た。
得られたフェライト焼結板の一方の表面にPETフィルムを貼付し、もう一方の表面に両面テープを貼付してフェライト焼結シートを得た。厚さは390μmであった。
Ni−Zn−Cu−Coフェライトの組成が、所定の組成になるように各酸化物原料を秤量し、ボールミルを用いて20時間湿式混合を行った後、混合スラリーを濾別・乾燥して原料混合粉末を得た。該原料混合粉末を870℃で3時間焼成して得られた仮焼成物をボールミルで粉砕し、本発明に係るNi−Zn−Cu−Coフェライト粉末を得た。
得られたフェライト焼結板の一方の表面にPETフィルムを貼付し、もう一方の表面に両面テープを貼付してフェライト焼結シートを得た。厚さは59μmであった。
Ni−Zn−Cu−Coフェライトの組成が、所定の組成になるように各酸化物原料を秤量し、ボールミルを用いて20時間湿式混合を行った後、混合スラリーを濾別・乾燥して原料混合粉末を得た。該原料混合粉末を810℃で3時間焼成して得られた仮焼成物をボールミルで粉砕し、本発明に係るNi−Zn−Cu−Coフェライト粉末を得た。
得られたフェライト焼結板の一方の表面にPETフィルムを貼付し、もう一方の表面に両面テープを貼付してフェライト焼結シートを得た。厚さは249μmであった。
組成と焼成温度を種々変化させた以外は実施例1と同様にしてフェライト焼結シートを得た。
Ni−Zn−Cuフェライトの組成が、所定の組成になるように各酸化物原料を秤量し、ボールミルを用いて20時間湿式混合を行った後、混合スラリーを濾別・乾燥して原料混合粉末を得た。該原料混合粉末を780℃で3時間焼成して得られた仮焼成物をボールミルで粉砕し、Ni−Zn−Cuフェライト粉末を得た。
得られたフェライト焼結板の一方の表面にPETフィルムを貼付し、もう一方の表面に両面テープを貼付してフェライト焼結シートを得た。厚さは211μmであった。
