以铜铁矿为原料，采用沉淀氧化法制备了磁性Fe 3 O 4颗粒。铁的收率为82.6at%。采用XRD、TEM、SEM、EDS和微波网络分析仪等手段对其进行了表征。结果表明：Fe 3 O 4颗粒结晶良好，具有八面体形貌，晶粒尺寸约为200 nm;当Fe 3 O 4含量为70wt%时，样品的吸波性能最佳，在14.08 GHz处反射损耗最小为− 42.7 dB，在厚度为1.9 mm时，小于− 10 dB的带宽约为4.2 GHz。结果表明，以铜铁矿为原料制备的Fe_3O_4颗粒可以作为一种有效的微波吸收材料。
In this study, magnetic Fe3O4particles were prepared from copper/iron ore cider by precipitation oxidization method. The yield of Fe was 82.6at%. XRD, TEM, SEM, EDS and microwave network analyzer were used to characterize the particles. The results showed that Fe3O4particles were well crystallized and possessed an octahedral morphology, and the crystal size was about 200nm; the sample with 70wt% Fe3O4exhibited the optimal absorbing ability, the minimum reflection loss was −42.7dB at 14.08GHz and the bandwidth less than −10dB was about 4.2GHz when the sample thickness was 1.9mm. It was clearly demonstrated that the Fe3O4particles prepared from copper/iron ore cider could be used as an effective microwave absorbing material.
