摘要
采用固相法制备Mn0.5Zn0.5Fe2O4锰锌铁氧体,通过XRD、SEM和网络分析仪研究样品的物相组成、微观形貌与电磁特性。结果表明:在1150℃下煅烧5h后可以制得纯相的锰锌铁氧体,颗粒分布均匀,大小约为250nm,并且Mn0.5Zn0.5Fe2O4铁氧体在11-15GHz频率范围内反射损耗RL小于-5dB,在13.8GHz处反射损耗达到了-12dB,表现出良好的吸波性能。
Mn-Zn ferrite Mn0.5Zn0.5Fe2O4 was prepared by the solid-phase method. The phase composition, micro-morphology and electromagnetic properties were studied by the XRD, SEM and network analyzer, respectively. The results showed that the pure Mn-Zn ferrite could be obtained after calcining at 1 150℃ for 5 h. The as-prepared particle performed a uniform particle size of about 250 nm. In addition, the reflection loss (RL) was less than -5 dB in the frequency range of 11-15 GHz, and the RL was reached to -12 dB in the frequency of 13.8 GHz, the as-prepared Mn-Zn ferrite exhibited excellent microwave absorption properties
