文摘

Metal-doped Ni-Zn ferrite with a spinel structure was directly synthesized from treated zinc-containing electric arc furnace dust (Zn-containing EAFD) by solid state reaction method, realizing the transformation of solid waste to high value-added material. First, NiCl2·6H2O was added to the treated Zn-containing EAFD before calcination. Then, the effects of the mass ratio of treated Zn-containing EAFD to NiCl2·6H2O (RTZE/N, g g−1) and the calcination temperature on the synthesis and magnetic properties of as-synthesized samples were systematically investigated by X-ray diffraction, Raman spectroscopy and physical property measurement. It was found that RTZE/N and calcination temperature significantly influenced the synthesis of single-phase spinel ferrite and their magnetic properties. Pure metal-doped Ni-Zn ferrite, exhibiting good magnetic properties of higher saturation magnetization (Ms, 60.5 emu g−1) and lower coercivity (Hc, 49.8 Oe), was obtained when the calcination temperature was controlled at 1100 °C for 2 h with a RTZE/N of 1:0.9.
