| 摘 要： | 采用固相烧结法,按不同配方制备了吸波材料(LiFe)xZn1-2xFe2O4(x=0.1、0.2、0.3、0.4、0.45、0.5),研究了Cr2O3、Al2O3等掺杂对(LiFe)0.45Zn0.1Fe2O4吸波特性的影响。结果表明,(LiFe)0.45Zn0.1Fe2O4吸波性能较好,而在(LiFe)0.45Zn0.1Fe2O4中掺入1%的Al2O3对增加-10dB带宽很有帮助。

| Abstract: | (LiFe)_xZn_(1-2x)Fe_2O_4(x=0.1、0.2、0.3、0.4、0.45、0.5) were prepared by a conventional solid-state reaction method,and the influence of Cr_2O_3 and Al_2O_3 additives on microwave absorption properties of(LiFe)_(0.45)Zn_(0.1)Fe_2O_4 was investigated. The results manifest that the(LiFe)_(0.45)Zn_(0.1)Fe_2O_4 has the best absorption property,and adding 1% Al_2O_3 to(LiFe)_(0.45)Zn_(0.1)Fe_2O_4 helps to broaden the bandwidth of reflection loss at-10dB. |
