Metal doped Ni-Zn ferrite with spinel structure was directly synthesized from treated zinc-containing electric arc furnace dust (Zn-containing EAFD) by a solid state reaction method, realizing the transformation of solid waste to high value-added material. In order to prepare single phase spinel ferrite, a certain mass of NiCl2•6H2O was added to the treated Zn-containing EAFD before calcination. The effects of treated Zn-containing EAFD to NiCl2•6H2O mass ratio (RTZE/N, g/g) and calcination temperature on the preparation and magnetic properties of metal doped Ni-Zn ferrite were systematically investigated by X-ray diffraction, Raman spectroscopy and Physical Property Measurement System. It is shown that single-phase metal doped Ni-Zn ferrite, which exhibited excellent magnetic properties of higher saturation magnetization (Ms, 60.5 emu/g) and lower coercivity (Hc, 49.8 Oe), could be obtained when the calcination temperature was controlled at 1100 oC for 2 h with RTZE/N of 1:0.9.
