| 摘 要： | 采用传统氧化物工艺,用精铁矿粉代替Fe2O3、用Mn3O4代替MnCO3制备出高性能功率软磁MnZn铁氧体,研究了精铁矿粉和Mn3O4制备MnZn铁氧体的固相反应及预烧温度、烧结温度和掺杂对样品磁性能的影响,选择合适的配方及制备工艺,用精铁矿粉和Mn3O4可以制备出综合性能达到日本TDK PC30材料性能水平的功率软磁MnZn铁氧体。此项目研究成功可使功率铁氧体成本大幅下降,促进精铁矿资源深度开发,具有显著的社会经济效益。

| Abstract: | Excellent MnZn power ferrite materials have been prepared with refined iron -mineral powders in place of Fe2O3 and Mn3O4 in place of MnCOs. The solid phase reaction of forming MnZn ferrite with refined iron- mineral powders and Mn3O4 has been studied. The proper sintering technology and substitution can prepare with refined iron- mineral powders and Mn3O4. MnZn ferrite,which properties are similar to PC30 of TDK in Japan. |
