摘　　要：研究六角型多晶铁氧体吸波材料的设计和工艺，采用离子联合取代的方法，制得的吸波材料为Ｂａ（Ｃｏ２ＴｉＺｎ）ｘＦｅ１２－４ｘＯ１９系列．该种材料具有很好的性能和电磁参数，能在２—３ｃｍ（８—１８ＧＨｚ）波段范围内具有１０ｄＢ带宽为４．２４—５．５ＧＨｚ的吸波性能．采用Ｘ射线分析与扫描电镜形貌分析，两者完全符合预计的结果．Design and technology of hexagonal polycrystalline ferrite materials with electron_wave_absorbing are dicussed in this paper. Ba(Co 2TiZn) x Fe 12-4 x O 19 series were obtained by the combined ion substitution method. Such materials possess excellant physical properties and electromagnetic parameters. They have a wide 10dB band of 4.24—5.5 GHz with a band width of 2—3cm. They have not only a high absorbalility but also a wide frequency band. The results of both X -ray diffraction and scanning micrograph analysis are in good agreement with calculated results.
