摘　　要：采用溶胶-凝胶法制备锌铁氧体和钡铁氧体,并研究其对雷达波的吸收性能。结果表明,在800℃煅烧1 h,得到了锌铁氧体;在900℃煅烧1 h,得到了钡铁氧体。钡铁氧体对雷达波的吸波性能较强,其在频率10 GHz、11 GHz的反射损耗分别为11.27 dB和12.01 dB。The zinc ferrite and the barium ferrite were prepared by sol - gel process. Their radar wave absorbing properties were study. The results indicate that the zinc ferrite was synthesized at 800℃ for 1 h and the barium ferrite was synthesized at 900℃ for 1 h. The absorption property of the barium ferrite was better than the zinc ferrite. The absorbing properties of the barium ferrite were 11.27 dB and 12.01 dB at 10 GHz and 11 GHz, respectively.
