WIDE-TEMPERATURE LOW-LOSS HIGH-STRENGTH MNZN POWER FERRITE, AND PREPARATION METHOD THEREFOR AND USE THEREOF
A wide-temperature low-loss high-strength MnZn power ferrite, and a preparation method therefor and the use thereof. The wide-temperature low-loss high-strength MnZn power ferrite is comprised of a main component and an auxiliary component, wherein the mass of the auxiliary component is 0.165-0.61 wt% of the main component; the main component comprises iron oxide, manganese oxide and zinc oxide; and the auxiliary component comprises a first auxiliary component and a second auxiliary component, the first auxiliary component being cobalt oxide, and the second auxiliary component comprising at least three of calcium carbonate, niobium oxide, vanadium oxide and molybdenum oxide. By means of adding the auxiliary component, especially adding cobalt oxide with a specific mass, the cooperative adjustment of the specific ratio of Fe2+ to Co2+ is achieved, and power consumption is ensured to be effectively reduced without being influenced by temperature changes, such that the prepared wide-temperature low-loss high-strength MnZn power ferrite can have, at 25-120°C, the characteristics of low loss, a high magnetic flux density and an increase in strength by 10% or more.
