锰锌铁氧体纳米粉体及其制备方法研究进展

Progress on preparation methods of nano-sized powders for Mn-Zn ferrites

锰锌(Mn-Zn)铁氧体是应用最广泛的软磁铁氧体材料。随着电子器件及产品逐渐向小型化、轻量化和节能化方向发展,对其中使用的磁性元件及材料如锰锌铁氧体提出了更高的要求,因此具有更优性能的Mn-Zn铁氧体纳米粉体得到广泛研究。作为一种新材料,纳米Mn-Zn铁氧体的研究已经成为磁性材料研究的热点领域。阐述了制备Mn-Zn铁氧体纳米粉体的合成方法,包括高效球磨法、溶胶-凝胶法、化学共沉淀法、微乳液法和水热法。介绍了各种方法的原理与应用。

Mn-Zn ferrite is one of the most widely used soft ferrites in electronic industry. With the rapid development of miniaturization, lighter weight and energy saving of magnetic power electronic devices, higher demands were proposed for Mn-Zn power ferrites so nano-sized powder of Mn-Zn ferrite attracts extensive researches. Thesynthesis method of nano-sized powder of Mn-Zn ferrite has been reviewed in this paper, mainly including high-energy ball milling, sol-gel, co-precipitation, microemulsion and hydrothermal processing. The principle and applications of these methods have been discussed.
