以NiCO 3·2Ni（OH）2·4 H2O、CuO、ZnO和Fe 2 O3为原料，采用机械力化学法合成了NiCuZn铁氧体粉体。采用扫描电子显微镜（SEM）、X射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）和振动样品磁强计（VSM）对样品的形貌和结构进行表征。结果表明，机械力化学处理对粉末混合物的反应物产生了多种结构和化学效应，在700°C退火2 h后可得到单相的Ni 0. 45 Cu 0. 05 Zn 0. 5 Fe 2 O 4。与传统烧结法相比，机械力化学法制备的样品具有更低的Ms和μi，表明样品具有更好的磁性能。
NiCuZn-ferrite powders were synthesized by mechanochemical treatments using NiCO3⋅2Ni(OH)2⋅4H2O, CuO, ZnO and Fe2O3as raw materials. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and vibrating sample magnetometer (VSM) were employed to evaluate the morphologies and structures of samples. The results indicated that the mechanochemical treatment produced several structural and chemical effects on reactants of the powder mixtures, and single phase Ni0.45Cu0.05Zn0.5Fe2O4could be obtained after annealed at 700°C for 2h. In comparison with the traditional firing method, the mechanochemical method benefited achieving the lower Msand μi, which indicated that the sample had better magnetic properties.
