Description
23℃での1kHzにおける初透磁率が1500以上、且つ10MHzにおける初透磁率が200以上の周波数特性を有するように、前記出発原料の酸化鉄は、鋼板の塩酸酸洗廃液を共沈法で不純物を除去してから噴霧焙焼することで、酸化マンガンは、マンガン鉱石の溶解後の晶析と再溶解及び不純物の濾過操作を反復することで精製を施し、Feに対する不純物質量比率が下記3式を満たす酸化鉄、
Al/Fe < 1.5×10−4
Cr/Fe < 1.5×10−4
Mg/Fe < 8.6×10−5
及びMnに対する不純物質量比率が下記2式を満たす酸化マンガン
Cr/Mn < 7.0×10−5
Ti/Mn < 1.4×10−4
としたものを用いることを特徴とするMn−Zn系フェライトの製造方法である。
Al/Fe < 1.5×10-4
Cr/Fe < 1.5×10-4
Mg/Fe < 8.6×10-5
且つ、酸化マンガンについては、Mnに対する不純物成分質量比率が下記2式を満たすようにすれば、10MHzの高周波域にわたる広い周波数域で高い透磁率を得ることができると考え、本発明を完成させたのである。
Ti/Mn < 1.4×10-4
なお、上記の限定範囲を超えると、前述のとおり、広い周波数域で高い透磁率を得ることができなくなる。
