摘要

Metal-doped Ni-Zn ferrite with 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 Zn-containing EAFD from solid waste to high value-added material. A certain mass of NiCl_2·6H_2O was added to the treated Zn-containing EAFD before calcination. Then the effects of the mass ratio of treated Zn-containing EAFD to NiCl_2·6H_2O (R_(TZE/N), g g~(-1)) and 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 System. It is indicated that R_(TZE/N) and calcination temperature had important influences on the synthesis of single-phase spinel ferrite and their magnetic properties. Pure metal-doped Ni-Zn ferrite, which exhibited 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 R_(TZE/N) of 1:0.9.
