Method for preparing manganese-zinc ferrite with high magnetic conductivity
The invention provides a method for preparing manganese-zinc ferrite with high magnetic conductivity. The preparation method comprises the following steps: weighing manganese chloride, zinc sulfate, cobalt chloride and ferric trichloride, and adding the raw materials into deionized water to prepare a mixed solution; adding a mixed alkali solution into the mixed solution, heating the mixture to react, and filtering, washing, drying, grinding and presintering a reaction product to obtain the cobalt-doped manganese-zinc ferrite with the chemical formula of MnxZnyCo1-x-yFe2O4; mixing cobalt-dopedmanganese-zinc ferrite with CaCO3, Nb2O5, TiO2, ZrO2 and Bi2O3, carrying out ball milling, granulating and molding; sintering the mixture, heating the mixture to 1250-1350 DEG C, carrying out heat preservation sintering for 2-4 hours, and carrying out furnace cooling to obtain the manganese-zinc ferrite with magnetic conductivity. The manganese-zinc ferrite is effectively doped through a chemicalcoprecipitation method, so that the magnetic conductivity of the manganese-zinc ferrite is greatly enhanced.
本发明提出了一种制备高磁导率锰锌铁氧体的方法，包括如下步骤：称取氯化锰、硫酸锌、氯化钴、三氯化铁，加入去离子水中配制成混合溶液，向所述混合溶液中加入混合碱溶液，加热反应，过滤，洗涤，干燥，研磨，预烧，即得化学式为MnZnCoFeO的钴掺杂锰锌铁氧体；将钴掺杂锰锌铁氧体与CaCO、NbO、TiO、ZrO、BiO混合，球磨，造粒，成型，再进行烧结，将温度升至1250‑1350℃，保温烧结2‑4h，随炉冷却，得到所述磁导率锰锌铁氧体。本发明通过化学共沉淀法对锰锌铁氧体进行有效掺杂，从而大大增强了锰锌铁氧体的磁导性能。
