浅谈MnZn铁氧体的发展现状

本文对使用最广泛的MnZn铁氧体的应用、配方、添加剂、生产工艺、发展现状等方面综合介绍了国内外对MnZn铁氧体材料的发展现状。通过不同的配方、添加不同的添加剂和使用不同的制备工艺可以获得性能不同的MnZn铁氧体。为了满足电子元器件的发展需求,今后MnZn铁氧体的发展趋势主要向着高频低功耗、高磁导率、高温高饱、磁通密度和小型化、片式的贴件磁性元器件方向发展。

In this paper,the application,formulation,additive,production technology and development status of the most widely used MnZn ferrite materials are comprehensively introduced.MnZn ferrite with different properties can be obtained by different formulations,adding different additives and using different preparation techniques.In order to meet the development requirements of electronic components,MnZn ferrites will mainly develop towards high-frequency,low power consumption,high permeability,high temperature,high saturation,magnetic flux density and miniaturized,chip attached magnetic components in the future.
