Iron-deficient formula soft magnetic manganese zinc ferrite material as well as preparation method and application thereof
The invention discloses an iron-deficient formula soft magnetic manganese zinc ferrite material as well as a preparation method and application thereof. The iron-deficient formula soft magnetic manganese zinc ferrite material comprises a main component and an auxiliary component, and the main component comprises the following components by mole percent: 43.5-48.5 mol% of Fe2O3, 30-35 mol% of MnO, and the balance of ZnO; and the auxiliary components comprise the following components: CaCO3, CuO, ZrO2, Bi2O3 and MoO3. According to the iron-deficient formula soft magnetic manganese zinc ferrite material disclosed by the invention, Fe2O3 with low molar percentage content (less than 50%) is matched with MnO and ZnO to serve as main components, so that the cut-off frequency of the magnetic conductivity of the manganese zinc ferrite material is improved, and the attenuation of the magnetic conductivity of the manganese zinc ferrite material at a high frequency band is improved; meanwhile, CaCO3, CuO, ZrO2, Bi2O3 and MoO3 are combined to promote grain growth, the magnetic conductivity of the manganese zinc ferrite material is improved, and meanwhile it is guaranteed that the manganese zinc ferrite material has high saturation flux density and high Curie temperature.
本发明公开了一种缺铁配方软磁锰锌铁氧体材料及其制备方法和应用。本发明的缺铁配方软磁锰锌铁氧体材料，包括主成分和副成分，其中主成分按摩尔百分数计包括以下组分：Fe2O3为43.5～48.5mol％、MnO为30～35mol％，余量为ZnO；副成分包括以下组分：CaCO3、CuO、ZrO2、Bi2O3和MoO3。本发明的缺铁配方软磁锰锌铁氧体材料，将低摩尔百分含量(＜50％)的Fe2O3与MnO和ZnO搭配作为主成分，来提高锰锌铁氧体材料磁导率的截止频率以改善其磁导率在高频段的衰减；同时结合CaCO3、CuO、ZrO2、Bi2O3、MoO3以促进晶粒生长，提高锰锌铁氧体材料的磁导率的同时并保证其具有较高的饱和磁感应强度和较高的居里温度。
