摘要: 采用氧化物法陶瓷工艺制备高磁导率MnZn铁氧体材料,经过电镜扫描,得到烧结样品的微观结构。针对高性能的高磁导率MnZn铁氧体材料,分析了不同预烧温度对高磁导率MnZn铁氧体微观结构及电磁性能的影响,研究了MnZn铁氧体微观结构对其磁导率的影响,得到了高磁导率MnZn铁氧体材料最佳预烧温度为960℃,及良好的微观结构有利于降低比损耗。960℃预烧样品经过1 400℃气氛烧结,可得到磁导率为9 500左右的高性能高导MnZn铁氧体材料。

Abstract: High initial permeability MnZn soft magnetic materials were fabricated by Oxide ceramic technology, and get microstructure of high initial permeability MnZn by Scanning Electron Microscope(SEM). Examined the effect of anneal temperature on the microstructure and magnetic properties of MnZn ferrite, And get that the anneal temperature of 960℃ is the best one for high initial permeability MnZn soft magnetic material, and get the initial permeability is about 9 500.
