Abstract

The invention discloses a manganese-zinc high-conductivity soft magnetic ferrite material, a preparation method and applications thereof, wherein the soft magnetic ferrite material comprises a main component and a sub-component, the main component comprises Fe2O3, MnO and ZnO, and the sub-component comprises Ca2CO3, Bi2O3, MoO3 and SiO2. According to the present invention, the soft magnetic ferrite material has a Curie temperature of 190 DEG C, a magnetic permeability (10 KHz, 0.1 V) of 9897, and a magnetic permeability (200 KHz, 0.1 V) of 10663; by optimizing the pre-firing temperature and the secondary ball milling process, the grain size and the compactness of the product can be well controlled; and by comprehensively controling the pre-firing temperature, the sintering temperature andthe particle size of the powder, the initial magnetic permeability is improved is increased, such that the product has a high Curie temperature, especially is suitable for working environments with atemperature of below 180 DEG C, and can be widely used in the preparation of vehicle electronic devices.
