| 摘 要： | 采用传统陶瓷工艺及通过调整主配方,成功研制出了二峰温度从25℃至140℃的一系列超高饱和磁通密度Mn-Zn铁氧体材料。结果显示,因为锰锌铁氧体材料的饱和磁通密度Bs取决于主配方以及致密度,超富铁主配方是获得超高Bs锰锌铁氧体材料的必要条件;在超富铁主配方中,增加Fe2O3含量或Zn O含量都会使二峰温度升高,与常规配方是完全相反的变化规律;二峰温度越高,最低损耗值越高、高温Bs越高、起始磁导率越低、相对密度越低。

| Abstract: | A series of ultra-highBs Mn-Zn ferrite materials with second peak temperatures from 25℃ to 140℃ are successfully developed by adjusting the main formula and traditional ceramic process. The results show that super rich iron main formula is necessary for obtaining MnZn ferrite materials with ultra-highBs, because of theBs of MnZn ferrite materials is determined by composition and density. The increase of Fe2O3 or ZnO content in the super rich iron main formula can increase the second peak temperature, exactly different from the variation of the conventional formula. The higher second peak temperature, the higher minimum loss value andBsvalue, and the lower initial permeability and relative density. |
