The invention discloses a manganese-zinc ferrite with wide temperature range, high initial permeability and high Curie temperature. The manganese-zinc ferrite comprises main components and auxiliary components, wherein the main components comprise 5.5 mol%-58 mol% of Fe2O3 and 18 mol%-23.5 mol% of ZnO, with the balance being MnO; and the auxiliary components comprise at least two selected from thegroup consisting of, on the basis of the total weight of the main components, 30 to 100 ppm of CoO, 50 to 200 ppm of NiO, 100 to 300 ppm of CuO, 200 to 1000 ppm of SiO2, 50 to 500 ppm of Bi2O3 and 0to 300 ppm of MgO. Through the design of a zinc-rich formula and a composite doping system and the adjustment of a special mixing and sintering process, the prepared manganese-zinc ferrite has ultrahigh initial permeability, a high Curie temperature, a wide working temperature range and excellent performance, and can meet the use requirements of existing miniaturized and light-weight electronic components.
本发明公开了一种宽温高初始磁导率高居里温度锰锌铁氧体，包括主体组分和辅助组分；主体组分包括FeO55.5～58mol%，ZnO 18～23.5mol%，其余为MnO；辅助组分按主体组分总重量计，包括CoO 30～100ppm、NiO 50～200ppm、CuO 100～300ppm、SiO200～1000ppm、BiO50～500ppm和MgO 0～300ppm中的至少2种。本发明通过富锌配方及复合掺杂体系的设计，特殊的混料烧结工艺的调整，使得所制备的锰锌铁氧体具有超高的初始磁导率、较高的居里温度和较宽的工作温度范围，性能优异，能够满足现有小型化、轻量化电子元器件的使用要求。
