FERRITE COMPOSITION, FERRITE SINTERED BODY AND ELECTRONIC COMPONENT
To provide: a ferrite sintered body capable of being suitably used in a high frequency band and having excellent mechanical strength; a composition thereof; and an electronic component having the composition.SOLUTION: A ferrite composition has a main component and a sub-component. The main component comprises: 40.5 to 50.0 mol% of iron oxide in terms of Fe2O3; 6.0 to 14.0 mol% of copper oxide in terms of CuO; 7.0 to 25.0 mol% of zinc oxide in terms of ZnO; and nickel oxide as the remainder. Based on 100 pts.wt. of the main component, the sub-component comprises: 3.1 to 10.0 pts.wt of cobalt oxide in terms of Co3O4; 0.5 to 4.0 pts.wt of tin oxide in terms of SnO2; and 0.50 pt.wt or less (including 0) of bismuth oxide in terms of Bi2O3. When A=(α-18)/β, where α is a content expressed by mol% of zinc oxide in terms of ZnO in the main component and β is a content by weight of cobalt oxide in terms of Co3O4 based on 100 pts.wt. of the main component, A is -3.5 or more and 1.0 or less.SELECTED DRAWING: Figure 1
【課題】高周波帯域において好適に用いられることが可能であり、しかも機械的強度にも優れたフェライト焼結体と、その組成物と、その組成物を有する電子部品を提供すること。【解決手段】主成分と副成分とを有するフェライト組成物である。主成分が、鉄酸化物をＦｅ２ Ｏ３ 換算で４０．５～５０．０モル％、銅酸化物をＣｕＯ換算で６．０～１４．０モル％、亜鉛酸化物をＺｎＯ換算で７．０～２５．０モル％、残部にニッケル酸化物を含有する。主成分１００重量部に対して、副成分が、コバルト酸化物をＣｏ３ Ｏ４ 換算で３．１～１０．０重量部、スズ酸化物をＳｎＯ２ 換算で０．５～４．０重量部、ビスマス酸化物をＢｉ２ Ｏ３ 換算で０．５０重量部以下(０を含む)で、含有する。主成分中の亜鉛酸化物のＺｎＯ換算でのモル％で表される含有量をα、主成分１００重量部に対するコバルト酸化物のＣｏ３ Ｏ４ 換算での重量部含有量をβとし、Ａ＝（α―１８）／βとする場合に、Ａは－３．５以上１．０以下である。【選択図】図１
