High-frequency high-direct-current-superposition low-loss manganese zinc ferrite material and preparation method thereof
The invention relates to a manganese zinc ferrite material with high frequency, high direct current superposition and low loss and a preparation method thereof. The preparation method of the high-frequency high-direct-current-superposition low-loss manganese-zinc ferrite material comprises the following steps: sequentially carrying out mixed grinding, primary pre-sintering, doping material adding, ball milling and granulation on the main materials, then adding secondary pre-sintering, secondary ball milling and secondary granulation treatment processes, preparing the material treated by the processes into a green body, and carrying out normal sintering and shaping, so as to obtain the high-frequency high-direct-current-superposition low-loss manganese-zinc ferrite material. The main materials comprise Fe2O3, MnO, ZnO and NiO, and the doping materials comprise CaCO3 and/or Nb2O5, TiO2 and/or Co2O3, Bi2O3 and/or SnO2. The prepared manganese zinc ferrite soft magnetic material has high saturation magnetic flux density, high Curie temperature and low power loss in a wide temperature range, a more stable inductance function can be realized in high-frequency and large-current application occasions, the provided preparation process is simple and suitable for mass production, and the energy consumption and the production cost can be effectively reduced.
