High-Bs low-power-consumption manganese-zinc soft magnetic ferrite material and preparation method thereof

CHEN JUN

The invention is applicable to the technical field of soft magnetic ferrite materials, and provides a high-Bs low-power-consumption manganese-zinc soft magnetic ferrite material and a preparation method thereof. The high-Bs low-power-consumption manganese-zinc soft magnetic ferrite material comprises 55.4-60.5 mol% of ferric oxide, 15.3-22.5 mol% of manganese oxide, 10.5-17.6 mol% of zinc oxide and 2.0-5 mol% of lithium carbonate. The soft magnetic ferrite material has the characteristics of high Bs and low power consumption, the high Bs characteristic can be fully utilized, and the temperature rise can also be met. Meanwhile, the material cost is far lower than that of a magnetic powder core material, and the performance and cost requirements of the high-power high-power-density power transformer design can be better met.

本发明适用于软磁铁氧体材料技术领域，提供了一种高Bs低功耗锰锌软磁铁氧体材料及其制备方法，包括三氧化二铁、氧化锰、氧化锌和碳酸锂，其中所述三氧化二铁含量为55.4‑60.5mol％，所述氧化锰含量为15.3～22.5mol％，所述氧化锌含量为10.5～17.6mol％，所述碳酸锂含量为2.0～5mol％；具有高Bs、低功耗的特点；可以充分利用其高Bs特性，并且温升也能得到满足；同时材料成本也远远低于磁粉芯材料，能更好的满足大功率高功率密度电源变压器设计的性能和成本需求。
