HEAT RESISTANCE AND HIGH MAGNETIC PERMEABILITY MnZn FERRITE
To provide heat resistance high magnetic permeability MnZn ferrite that has less decrease of original high relative initial magnetic permeability even when using it at a high temperature environment equal to or higher than 100°C continuously for a long term.SOLUTION: The heat resistance high magnetic permeability MnZn ferrite is MnZn ferrite including FeO, ZnO and MnO as main constituents in such an amount that, in the main constituent of 100 mol%, has FeOof 50.50 to 54.00 mol%, ZnO of 11.00 to 18.00 mol%, and MnO of the remainder. The heat resistance high magnetic permeability MnZn ferrite includes, as accessory constituents, CoOof 0.10 to 0.55 pts.mass, SnOof 0.50 to 4.00 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, based on 100 pts.mass of a total amount of the main constituent.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、該主成分１００ｍｏｌ％中、Ｆｅ２Ｏ３を５０．５０〜５４．００ｍｏｌ％、ＺｎＯを１１．００〜１８．００ｍｏｌ％、残部のＭｎＯとなる量で含有し、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、ＳｎＯ２を０．５０〜４．００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
