FERRITE SINTERED BODY AND WIRE-WOUND COIL COMPONENT
To provide a ferrite sintered body having high flexural strength after thermal shock and high cross-point frequency.SOLUTION: A ferrite sintered body contains Fe by 48.2 to 49.7 mol% in terms of Fe2O3, Cu by 2.0 to 8.0 mol% in terms of CuO, Ni by 17.7 to 24.0 mol% in terms of NiO, and Zn by 21.0 to 28.0 mol% in terms of ZnO. When Fe, Cu, Ni, and Zn are converted to Fe2O3, CuO, NiO, and ZnO, respectively, and when the total amount of the Fe2O3, the CuO, the NiO, and the ZnO is 100 pts.wt., the ferrite sintered body contains B by 5 to 25 ppm in terms of elemental B and Nb of 6 to 25 ppm in terms of elemental Nb.SELECTED DRAWING: None
【課題】熱衝撃後の抗折強度が高く、かつ、クロスポイント周波数が高いフェライト焼結体を提供する。【解決手段】ＦｅをＦｅ２Ｏ３に換算して４８．２ｍｏｌ％以上、４９．７ｍｏｌ％以下、ＣｕをＣｕＯに換算して２．０ｍｏｌ％以上、８．０ｍｏｌ％以下、ＮｉをＮｉＯに換算して１７．７ｍｏｌ％以上、２４．０ｍｏｌ％以下、ＺｎをＺｎＯに換算して２１．０ｍｏｌ％以上、２８．０ｍｏｌ％以下含有し、Ｆｅ、Ｃｕ、ＮｉおよびＺｎをそれぞれＦｅ２Ｏ３、ＣｕＯ、ＮｉＯおよびＺｎＯに換算し、上記Ｆｅ２Ｏ３、上記ＣｕＯ、上記ＮｉＯおよび上記ＺｎＯの合計量を１００重量部としたときに、ＢをＢ単体に換算して５ｐｐｍ以上、２５ｐｐｍ以下、ＮｂをＮｂ単体に換算して６ｐｐｍ以上、２５ｐｐｍ以下含有する、フェライト焼結体。【選択図】なし
