摘　　要：本文利用传统陶瓷制备工艺制备了Ni-Zn铁氧体材料,用SEM,XRD观察其微观结构,使用Agilent 4294A阻抗分析仪检测样品的磁性能.研究了不同烧结温度对Ni0.4Zn0.6Fe2O4材料的起始磁导率、功耗和显微结构的影响.结果表明,在1 250℃烧结时试样有较好的综合性能,不仅具有较高的磁导率而且损耗也较小.Ni-Zn ferrite materials were prepared by traditional ceramic preparation technology. SEM and XRD were used to observe the microstructure and the magnetic properties was tested by Agilent 4294A impedance analyzer. The influence of sintering temperature on the initial permeability,power loss and microstructure of the Ni0. 4Zn0. 6Fe2O4ferrite materials was investigated. When sintered at1 250 ℃,Ni-Zn ferrites present better overall performance,high magnetic permeability and low loss.
