HEAT-RESISTANT HIGH MAGNETIC PERMEABILITY MnZn FERRITE
To provide heat-resistant high magnetic permeability MnZn ferrite that suppresses the deterioration of a specific initial magnetic 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: There is provided MnZn ferrite including FeO, ZnO and MnO as main constituents. In the main constituent of 100 mol%, the MnZn ferrite has FeOof 50.60 to 53.70 mol%, ZnO of 18.00 to 20.00 mol%, and MnO of the remainder. When the total amount of the main constituents is set to 100 pts.mass, the MnZn ferrite includes CoOof 0.10 to 0.55 pt.mass, BiOof 0.001 to 0.030 pt.mass, MoOof 0.001 to 0.020 pt.mass, SiOof 0.001 to 0.010 pt.mass, and CaO of 0.015 to 0.030 pt.mass as accessory constituents, and further includes either one or both of TiOof 0.10 to 2.50 pts.mass, and SnOof 0.50 to 4.00 pts.mass.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５０．６０〜５３．７０ｍｏｌ％、ＺｎＯを１８．００〜２０．００ｍｏｌ％、残部のＭｎＯとなる量で含有し、前記主成分の全量を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、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質量部含有し、さらに、ＴｉＯ２を０．１０〜２．５０質量部、および、ＳｎＯ２を０．５０〜４．００質量部、のいずれか一方または両方を含有する、ＭｎＺｎフェライトを用いる。【選択図】なし
