纳米钡铁氧体制备新进展

New developments in the preparation of nano barium ferrite

阐述了国内外纳米钡铁氧体制备技术的研究进展。纳米钡铁氧体在磁性和吸波性能等方面都展现了优异的特性,具有广阔的应用前景。近年来出现了很多纳米钡铁氧体制备新工艺,溶胶-凝胶法因其在控制产品的成分及均匀性方面具有独特的优越性而成为纳米钡铁氧体粉体和薄膜的主要制备方法,但有些新工艺的机理还需深入研究。分析表明纳米钡铁氧体的制备还需进一步完善,并提出纳米钡铁氧体与导电聚合物的复合、纳米钡铁氧体的掺杂及掺杂后与导电聚合物的复合是纳米钡铁氧体制备的研究方向。

The technology research on nano-barium ferrite preparation progress was reviewed.Nano-barium had broad application prospect for its excellent ferrite magnetic and microwave absorbing properties.In recent years many nano-barium ferrite preparation process,sol-gel method were proposed for the preparation of nano-barium ferrite powder and film because of its unique superiority in the control of product composition and uniformity,but some new technology mechanism needs further study.The analysis shows that the nano-barium ferrite preparation needs to be further improved.The nano-barium ferrite and conductive polymer composites,nano-barium ferrite doping,nano barium ferrite doped and conductive polymer composites shall be further investigated in future.
