摘要: 采用固相烧结法,按不同配方制备了吸波材料（LiFe）_xZn_1-2xFe₂O₄(x=0.1、0.2、0.3、0.4、0.45、0.5),研究了Cr₂O₃、Al₂O₃等掺杂对(LiFe)_0.45Zn_0.1Fe₂O₄吸波特性的影响。结果表明,LiFe)_0.45Zn_0.1Fe₂O₄吸波性能较好,而在LiFe)_0.45Zn_0.1Fe₂O₄中掺入1%的Al₂O₃对增加-10dB带宽很有帮助。

Abstract: (LiFe)_xZn_1-2xFe₂O₄(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 Cr₂O₃ and Al₂O₃ additives on microwave absorption properties of(LiFe)_0.45Zn_0.1Fe₂O₄ was investigated. The results manifest that the(LiFe)_0.45Zn_0.1Fe₂O₄ has the best absorption property,and adding 1% Al₂O₃ to(LiFe)_0.45Zn_0.1Fe₂O₄ helps to broaden the bandwidth of reflection loss at-10dB.
