一种高频低损耗软磁铁氧体磁芯材料的制备方法
摘要：
本发明公开了一种高频低损耗软磁铁氧体磁芯材料的制备方法，该软磁铁氧体磁芯材料由Fe2O3、ZnO、Al2O3、NiO、Co2O3、WO3、ZrO2、Pr6O11、La2(CO3)3、V2O5、MnCO3、Bi2O3、Li2CO、TiB2、Cr3C2等原料组成；本发明材料通过一次配料、一次球磨、一次烧结、二次配料、二次球磨、压制成型、二次烧结等步骤制成。本发明添加的Co2O3、WO3、ZrO2、Pr6O11、TiB2、Cr3C2等成分不仅可以提高的使用频率和温度稳定性，还可以降低其磁损耗，使制得的软磁铁氧体磁芯材料具有较低的高频损耗率，在100kHz高频下损耗因数低于1.6×10－6。
摘要（英）：

The invention discloses a preparation method of a high frequency low loss soft magnetic ferrite core material. The soft magnetic ferrite core material is formed by the raw materials such as Fe2O3, ZnO, Al2O3, NiO, Co2O3, WO3, ZrO2, Pr6O11, La2(CO3)3, V2O5, MnCO3, Bi2O3, Li2CO, TiB2 and Cr3C2. The material is prepared by the following steps of primary batching, primary ball milling, primary sintering, secondary batching, secondary ball milling, compression moulding, secondary sintering and the like. The Co2O3, the WO3, the ZrO2, the Pr6Oll, the TiB2, the Cr3C2 and other components are added, so that not only can the use frequency and the temperature stability be improved, but also the magnetic loss can be reduced, the prepared high frequency low loss soft magnetic ferrite core material has lower high frequency loss, and the loss factor is lower than 1.6*10<-6> at the high frequency of 100kHz.
