Abstract

The invention discloses a wide temperature, low power consumption and high permeability manganese zinc ferrite material and a preparation method thereof. The material comprises a main component and adoping component, wherein the main component comprises the following components in percentage by mass: 55.8 to 58.7 percent of Fe2O3, 9.8 to 11.2 percent of ZnO, the balance of MnO, and the total amount is 100 percent. The material ensures that grains are sufficiently refined by relatively reducing the content of Fe2O3 in the main component and through a special doping technology, reduces the probability of irregular large grains, effectively improves the power consumption, meanwhile broadens the operating temperature range, has excellent properties of wide temperature, low power consumption and high permeability, is beneficial to the miniaturization of transformer devices, reduces the industrial scale production cost, and improves the operating efficiency.
