摘　　要：通过草酸盐共沉淀法制备了纳米级别的NiCuZn铁氧体粉末,采用X射线衍射和振动样品磁强计分析研究了不同煅烧温度对试样的微观结构和饱和磁化强度的影响。试验结果表明:通过草酸盐共沉淀法制备的Ni0.4Cu0.2Zn0.4Fe2O4铁氧体粉末,在一定煅烧条件下能够得到单一尖晶石相的粉末;随着煅烧温度的增加,试样的饱和磁化强度增加,矫顽力减小。In this paper,NiCuZn ferrite nanoparticles were prepared by oxalate co-precipitation. The influence of the different calcination temperature on the microstructure and saturation magnetization were investigated by X-ray diffraction and vibrating sample magnetometer. The results showed that：Ni0.4Cu0.2Zn0.4Fe2O4 ferrite powder prepared by oxalate co-precipitation can be obtained a single phase of spinel in a certain calcined conditions. As the calcination temperature increases,the saturation magnetization of the sample increased while the coercive force decreased.
