Preparation and Characterization of Manganese-Zinc Ferrites by a Solvothermal Method

Keywords： Mn-Zn ferrites , solvothermal method , magnetic property , microstructures , morphology

用溶剂热法合成了锰锌铁氧体,并用XRD,SEM,VSM对其进行了性能表征.本实验还系统研究了溶剂热合成条件如锰锌元素比,溶剂热温度,溶剂热时间对实验所得样品形貌以及性能的影响.结果表明,当温度为160和180℃时,并未形成锰锌铁氧体,锰锌铁氧体的形成温度为200℃;随着溶剂热时间的延长,锰锌铁氧体颗粒变得更加均匀且粒径变大,饱和磁化强度增加;锰锌铁氧体中锰元素的增加不会显著改变锰锌铁氧体的形貌,却可以使得锰锌铁氧体的饱和磁化强度增加.
