Wide-temperature low-medium-frequency low-loss MnZn ferrite and preparation method thereof
The invention provides wide-temperature low-medium-frequency low-loss MnZn ferrite and a preparation method thereof.The ferrite is formed by secondary sintering of a main component and an auxiliary modifier, the auxiliary modifier is mainly composed of nanometer calcium oxide, nanometer silicon oxide, vanadium oxide, titanium oxide, niobium oxide and other oxides, the main component and the auxiliary modifier are compounded, and therefore the high-loss MnZn ferrite is obtained. The ferrite is prepared by adopting a secondary sintering mode, so that the crystal form and the particle size range of the ferrite can be controlled in the sintering process, the growth stability of ferrite crystals is ensured, the size of the formed crystals is reduced, the porosity in the ferrite is reduced, and the method has the advantages of effectively promoting the development of a transformer towards the miniaturization and light weight direction, improving the production efficiency and the like. The transformer has the advantages that the applicability of the transformer is improved, the use requirement for reducing iron core loss of the transformer under the conditions of medium-low frequency and high temperature can be met, the implementation and improvement cost is low, and popularization and implementation are convenient.
