摘要  结合化学共沉淀方法制备了CoZn X型六角晶系钡铁氧体,对其结构、显微形貌和磁性的测量分析表明:Zn的加入有利于促进CoZn X型钡铁氧体相的形成及晶粒长大,也有利于提高饱和磁化强度;适当的Zn含量可以使CoZn X型钡铁氧体具有高频软磁特性,经1320℃×3h烧结后样品的起始磁导率随Zn含量增加在x=1.0处有极大值15,对应截止频率140MHz。 CoZnX type barium hexaferrites were prepared by chemical coprecipitation method and sintering in air. The structures, morphologies and magnetic properties of sintered samples were investigated. It was shown that the saturation magnetization of CoZnX barium hexaferrites can be promoted by adding Zn. Highfrequency soft magnetic properties with high permeability can be obtained with proper Zn content. The initial permeability could reach maximum value 15 with cutoff frequency 140MHz at x=1.0 when it was sintered at 1320℃ for 3h.
