摘要
围绕锰锌铁氧体的尖晶石结构和性能的关系,分析了锌含量、晶粒尺寸、晶界等微观结构参数以及微量元素掺杂等主要因素对锰锌铁氧体结构性能的影响。介绍了今后软磁铁氧体研究的主要方向、性能要求、国内外的研究情况及最新进展。近期研究表明,目前国内外除注重功率型和高磁导率锰锌铁氧体的研究之外,还比较关注锰锌铁氧体的改性研究及其在纳米科技领域的应用和用废旧材料为原料的环保节能型新工艺;锰锌铁氧体今后将进一步向高频、高磁导率和低损耗方向发展,同时注重材质特性的适应性和生产工艺的优化。
The influences of the content of Zn, parameters of microstructure such as size and interphase of crystal and the dopants on the relationship between structure and magnetic properties of Mn-Zn ferrite are analyzed. The requirements are reviewed with reference to the current research situation and development. At present, researches on modification of Mn-Zn ferrite and its applictation in nano technology field are concerned besides the developments of power ferrites and high permeability ferrites. In addition, the investigation on using waste materials especially attracts attention. The trend henceforth is still high power and permeability and low loss as well as adjustability and optimization of process.
