    New search for: KADOWAKI MAKOTO
    New search for: KOYUHARA TOKUKAZU

    To obtain useful MnZn based ferrite powder in a high frequency region.SOLUTION: MnZn based ferrite powder includes: 53-56 mol% of Fe in terms of Fe2O3, 3-9 mol% of Zn in terms of ZnO and a remainder Mn in terms of MnO as a main component; and 0.05-0.4 pt.mass of Co in terms of Co3O4 to the total 100 pts.mass of the main component in terms of the oxide as a sub-component. The MnZn based ferrite powder having a surface on which two fracture modes of transgranular fracture and intergranular fracture mix with each other is obtained by coarsely and finely pulverizing a sintered body subjected to heating and passing through a sieve having an opening of 190 μm.SELECTED DRAWING: Figure 3

    【課題】 高周波数領域において、有用なＭｎＺｎ系フェライト粉を得る。【解決手段】Ｆｅ２Ｏ３換算で５３～５６モル％のＦｅ、ＺｎＯ換算で３～９モル％のＺｎ及びＭｎＯ換算で残部Ｍｎを主成分として含み、前記酸化物換算での前記主成分の合計１００質量部に対して、Ｃｏ３Ｏ４換算で０．０５～０．４質量部のＣｏを副成分として含むＭｎＺｎ系フェライト粉。前記ＭｎＺｎ系フェライト粉は、粒内破壊、粒界破壊の両方の破壊モードが混在した表面を有する。前記ＭｎＺｎ系フェライト粉は、熱処理した焼結体を粗粉砕して、微粉砕して目開き１９０μｍの篩を通過している。【選択図】図３
