摘　　要：利用钢板酸洗废液、镍电镀废液、铜电镀废液及锌电镀废液,以适量各废液调配,以ICP-AES检测其浓度,经化学共沉法而获得镍铜锌铁氧磁粉,热处理使晶粒长大,增大模具成型生胚密度,经烧结得环状体,测量其性质,经XRD,SEM,TEM及VSM等检测分析,实验结果显示镍铜锌铁氧磁粉晶体为尖晶石立方结构,晶粒大小为8～20nm,饱和磁束密度为31.6emu/g,经过750℃热处理饱和磁束密度为52.3emu/g.烧结环状体晶粒大小为1～3μm,饱和磁束密度为60.7emu/g(3670 Gauss).Ni-Cu-Zn ferrite powder prepared by coprecipitation method using steel pickling liquor,nickel,copper,and zinc electroplating waste solutions as raw materials was studied.The crystalline phase,magnetic property,particle shape and size of the Ni-Cu-Zn ferrite powder and the sintered bodies were measured.The powder prepared by the coprecipitation process showed the formation of spinel cubic structure with a saturation magnetization(Ms) of 31.6 emu/g and the particle size of 8～20 nm.The saturation magnetization of the sintered toroid core with the grain size of 1～3 μm is 60.7 emu/g(3670 Gauss).
