Ferrite composition, ferrite sintered body, and electronic component
Provided are: a ferrite sintered body which is suitable for use in a high-frequency band and has excellent mechanical strength; a composition; and an electronic component containing the composition. The ferrite composition comprises: a main component containing 40.5-50.0 mol% of an iron oxide in terms of Fe2O3, 6.0-14.0 mol% of a copper oxide in terms of CuO, 7.0-25.0 mol% of a zinc oxide in terms of ZnO, and the balance of a nickel oxide; and an auxiliary component containing 3.1-10.0 parts by weight of a cobalt oxide in terms of Co3O4, 0.5-4.0 parts by weight of a tin oxide in terms of SnO2, and 0.50 parts by weight or less and 0 part by weight of a bismuth oxide in terms of Bi2O3 relative to 100 parts by weight of the main component. In the main component, the content of the zinc oxide is alpha in mol% in terms of ZnO, the content of the cobalt oxide is beta in terms of parts by weight in terms of Co3O4 with respect to 100 parts by weight of the main component, and when A = (alpha-18)/beta, A is from-3.5 to 1.0 (inclusive).
提供高频频带适用且机械强度优异的铁氧体烧结体、组合物和含组合物的电子部件。铁氧体组合物具有：含有Fe2O3换算40.5～50.0摩尔％的铁氧化物、CuO换算6.0～14.0摩尔％的铜氧化物、ZnO换算7.0～25.0摩尔％的锌氧化物和余部镍氧化物的主成分；和相对主成分100重量份含有Co3O4换算3.1～10.0重量份的钴氧化物、SnO2换算0.5～4.0重量份的锡氧化物、Bi2O3换算0.50重量份以下且含0的铋氧化物的副成分。主成分中锌氧化物以ZnO换算的摩尔％表示含量为α，钴氧化物相对主成分100重量份以Co3O4换算的重量份含量为β，A＝(α－18)/β时，A为－3.5以上1.0以下。
