HEAT-RESISTANT HIGH PERMEABILITY MnZn FERRITE
To provide heat-resistant high-permeability MnZn ferrite that suppresses the deterioration of a specific initial permeability being initially high, even when it is used continuously for a long term at high temperature environment higher than or equal to 100°C.SOLUTION: The heat-resistant high-permeability MnZn ferrite is MnZn ferrite that has FeO, ZnO and MnO as main constituents, and includes 50.50 to 54.00 mol% of FeO, 11.00 to 18.00 mol% of ZnO, and the balance MnO, all of which totals 100 mol%. When the total amount of the main constituents is set to 100 pts.mass, the heat-resistant high-permeability MnZn ferrite includes CoOof 0.10 to 0.55 pts.mass, TiOof 0.10 to 2.50 pts.mass, BiOof 0.001 to 0.030 pts.mass, MoOof 0.001 to 0.020 pts.mass, SiOof 0.001 to 0.010 pts.mass, and CaO of 0.015 to 0.030 pts.mass, as accessory constituents.SELECTED DRAWING: None
【課題】１００℃以上の高温環境で長期間継続して使用した場合にも当初の高い比初透磁率の低下が少ない耐熱性高透磁率ＭｎＺｎフェライトを提供する。【解決手段】Ｆｅ２Ｏ３とＺｎＯとＭｎＯを主成分とするＭｎＺｎフェライトであって、Ｆｅ２Ｏ３を５０．５０〜５４．００ｍｏｌ％、ＺｎＯを１１．００〜１８．００ｍｏｌ％、残部のＭｎＯを合わせて１００ｍｏｌ％となるように含有し、主成分の全量を１００質量部としたときに、副成分としてＣｏ２Ｏ３を０．１０〜０．５５質量部、ＴｉＯ２を０．１０〜２．５０質量部、Ｂｉ２Ｏ３を０．００１〜０．０３０質量部、ＭｏＯ３を０．００１〜０．０２０質量部、ＳｉＯ２を０．００１〜０．０１０質量部、およびＣａＯを０．０１５〜０．０３０質量部含有することを特徴とする耐熱性高透磁率ＭｎＺｎフェライト。【選択図】なし
