Composite ferrite material as well as preparation method and application thereof
The invention relates to a composite ferrite material and a preparation method and application thereof, and the preparation method comprises the following steps: according to molar percentage, weighing by oxide to obtain a MnZn ferrite main material; according to the weight percentage, calculating by oxide, and weighing to obtain a first additive; weighing according to the weight percentage to obtain a second additive; putting the MnZn ferrite main material into a ball mill for grinding, then pre-sintering, and drying a ball-milled material obtained after primary ball milling; adding a first additive and a second additive, then carrying out secondary ball milling, adding an organic binder into the powder after secondary ball milling, uniformly mixing, granulating, then pressing into a green body, and sintering the green body to obtain the composite ferrite material. Starting from the electromagnetic performance of the material, the direct current superposition resistance of the material is improved, so that the magnetic conductivity of the magnetic core can be kept unchanged in a certain direct current magnetic field.
