| 摘 要： | 采用固相烧结工艺,按不同配方分别制备了(LiFe)xZn1-2xFe2O4(x=0.1、0.2、0.3、0.4、0.45、0.5),用Agilent8510c矢量网络分析仪测试,在0.5～13GHz频段内材料的吸波性能.实验发现(LiFe)0.45Zn0.1Fe2O4有较强的吸波性能,然后再对(LiFe)0.45Zn0.1Fe2O4进行不同搀杂,并在0.5～18GHz频段内测试材料的吸波性能,发现掺入1wt%的Al2O3对增加-10dB带宽非常有效果.

| Abstract: | (LiFe)xZn1-2xFe2O4(x=0.1、0.2、0.3、0.4、0.45、0.5) were prepared by a conventional solid-state reaction method,The absorption properties were measured using a Agilent8510 vector network analyzer in frequency range of 0.5~13GHz,It is found that the absorption property of(LiFe)0.45Zn0.1Fe2O4 is better.and studing the influences of Cr2O3 and Al2O3 additives in(LiFe)0.45Zn0.1Fe2O4 on microwave absorption properties,then found that Al2O3(1wt%) doping can increases-10dB bandwidth. |
