| 摘 要： | 本文用溶胶-凝胶自燃烧法制备了Ni0.5Zn0.5Fe2O4粉末颗粒,以甲醛为还原剂在Ni0.5Zn05Fe2O4颗粒表面进行了化学镀铜,制备了Cu/Ni0.5Zn0.5Fe2O4复合粉体.用扫描电镜(SEM)、能谱仪(EDS)和X射线衍射仪(XRD)对镀铜前的Ni0.5Zn0.5Fe2O4颗粒以及镀铜后的复合纳米颗粒进行了表征.对镀铜前的Ni0.5Zn0.5Fe2O4粉体和不同镀铜量的Cu/Ni0.5Zn0.5Fe2O4复合粉体进行了电磁性能的研究,结果表明镀铜后镍锌铁氧体的吸波性能明显提高,增重量为65%的Cu/Ni0.5Zn0.5Fe2O4复合粉体在频率为11GHz处反射率可达-12dB左右.

| Abstract: | The composite powders of Ni_(0.5)Zn_(0.5)Fe_2O_4 with Cu covered by electroless plating technique were prepared.The components and morphology of the powders were studied by scanning electron microscopy(SEM),energy dispersive spectrometry(EDS) and X-ray diffraction(XRD) analysis.It was indicated that the pure Ni_(0.5)Zn_(0.5)Fe_2O_4 had the structure of spinelle and the chemical composition of the plating layer on the surface of Ni_(0.5)Zn_(0.5)Fe_2O_4 was copper.The electromagnetic parameters of the powders were measured in the condition of different thickness of plating layer.It was showed that the absorbing action of Cu/Ni_(0.5)Zn_(0.5)Fe_2O_4 to electromagnetic parameters increased obviously after the eletroless copper plating. |
