Iron-manganese-zinc ferrite material as well as preparation method and application thereof
The invention provides an iron-manganese-zinc ferrite material as well as a preparation method and application thereof. The iron-manganese-zinc ferrite material comprises main components and auxiliary components, the main component is prepared from the following components in percentage by mass: 68 to 71 weight percent of Fe2O3, 11 to 15 weight percent of ZnO and the balance of Mn3O4; the auxiliary component comprises any one of CaCO3, Bi2O3, TiO2 or MoO3 or a combination of at least two of the CaCO3, the Bi2O3, the TiO2 or the MoO3. The iron-manganese-zinc ferrite material provided by the invention has low stress sensitivity, high initial permeability and broadband high impedance, so that the inductance drop proportion of a magnetic core made of the iron-manganese-zinc ferrite material is relatively small under the condition that the magnetic core is subjected to the same stress.
本发明提供了一种铁锰锌铁氧体材料及其制备方法与应用，所述铁锰锌铁氧体材料包括主成分与辅成分；以所述主成分的质量为百分百计，所述主成分包括质量分数为68～71wt％的Fe2O3，质量分数为11～15wt％的ZnO，余量为Mn3O4；所述辅成分包括CaCO3、Bi2O3、TiO2或MoO3中的任意一种或至少两种的组合。本发明提供的铁锰锌铁氧体材料具有低应力敏感性、高初始磁导率与宽频高阻抗，从而使得所述铁锰锌铁氧体材料制作的磁芯在受到相同应力的情况下电感跌落的比例较小。
