摘　　要：综述了近年来超高频用Z型六角铁氧体材料的研究现状,着重讨论了Z型六角铁氧体的低温烧结及其应用。采用固相反应法制备的低温烧结Z型六角铁氧材料的磁导率较低（2~4）,而溶胶-凝胶法制备的材料的磁导率一般在5~8,但存在成本高、污染环境等问题。并从应用的角度对Z型六角铁氧体电磁性能的改善途径进行了总结。The research present status of Z-type hexaferrite for UHF band applications is reviewed,and low-temperature sintering and application of Z-type hexaferrite are mainly discussed.The initial permeability of low-temperature-sintered Z-type hexaferrite prepared by solid state reaction method is low（2-4）;though the initial permeability of the material prepared by Sol-gel method is up to 5-8,however some problems such as high cost,environmental pollution exist.The measures of improving Z-type hexaferrite electromagnetic properties are summarized from application points of view.
