    摘要:

    用柠檬酸溶胶凝胶法制备了Cu、Zr 共掺钡铁氧体前驱体,研究煅烧温度对其物相的影响及Cu、
    Zr 共掺对其吸波性能的影响。研究发现前驱体[BaFe11. 2(Cu0. 5 Zr0. 5 )0. 8 O19 ] 在1 200℃煅烧1 h,得到了单相的钡铁氧体。随着Cu、Zr 掺量的增加,铁氧体的吸波性能提高。当Cu、Zr 掺入量为0. 8 时,铁氧体的吸波性能最
    好,在10. 4 GHz 时,最大反射损耗达-7. 81 dB。

    Abstract:

    The barium ferrite precursors gels were prepared with sol-gel process by using citric acid. The effect
    of calcination temperature on its phase and the effect of multiple doping(Zr, Cu) on microwave absorbing properties were studied. The barium ferrite was synthesized at 1 200 for 1 h. The absorption properties of the ferrite could be improved by increasing doping content. The absorbing properties of the ferrite is the best,with reflection loss of -7. 81 dB at 10. 4 GHz when the content of copper and zirconium is 0. 8 (BaFe12-x(Cu0. 5Zr0. 5)x O19,x =0. 8).
