Electric arc furnace dust (EAFD) and waste pickle liquor (WPL); two major side products of the steel industry with negative environmental impact were used for the synthesis of nickel zinc ferrite (NZF); the important magnetic ceramic material of versatile industrial applications. The structural and magnetic properties of the prepared material were examined which showed good magnetic properties (high saturation magnetization and low coercivity) compared with those synthesized from pure reagents. In the applied process, nano sized nickel zinc ferrite (NZF) with a composition of Nix(Zn + impurities)1−xFe2O4 (where x = 0, 0.25, 0.5, 0.75 and impurities of manganese, magnesium, and calcium were prepared using zinc-containing electric arc furnace dust (EAFD) and waste pickle liquor (WPL). The chemical compositions of the prepared samples were determined using X-ray fluorescence (XRF) analysis. The optimum acetic acid concentration for EAFD treatment was found 2% v/v that decreased Ca content of EAFD by 70.6% without loss of Fe and Zn. The structural and morphological characterization was done by X-ray diffraction (XRD), Fourier transform infrared (FTIR) and Field Emission Scanning Electron Microscope (FESEM) to confirm the formation of Ni–Zn ferrite nanoparticles and estimate the particle sizes. The maximum saturation magnetization (Ms) of 73.89 emu/g was achieved at 0.5 Ni content and the minimum coercivity of 2.55 Oe was obtained at 0.25 Ni content.

“…In the spinel ferrites family, magnesium ferrite (MgFe 2 O 4 ) has a spinel structure with inversion mode that depends on the synthesis method used in memory and switching circuits. Magnesium ferrite is used in heterogeneous catalysis, adsorption, sensors, and magnetic technologies (1)(2)(3)(4) . The non-magnetic Cu resides in a tetrahedral (A) site whose doping can modify the structural, electrical, and magnetic properties (5)(6)(7) .…”

Objective: To prepare Cu doped Mg 0.5−x Cu x Zn 0.5 Fe 2 O 4 (x = 0.0, 0.05, 0.1, 0.15, 0.2 and 0.25) spinel ferrites materials and study the structure, morphology, and magnetic properties. Methods: Cu doped Mg-Zn spinel ferrites are magnetic and highly resistive materials. They were synthesized by the method of solid-state reaction and characterized by x-ray diffraction (XRD), field effect scanning electron microscopy (FESEM), Fourier transform infrared (FTIR), and vibrating sample magnetometer (VSM) for their structural, compositional, morphological, functional properties. They are with spinel structure under Fd-3m space group. Their crystallite size was 44.58 nm to 31.02 nm range after calcined at 1000 o C. Their spinel structure was confirmed with FT-IR analysis, whose absorption bands were 598.84 -580.40 cm -1 and 405.35 -402.15 cm -1 range for higher and lower frequency, respectively. The value of coercivity is in the range 146.33 -9.427 Oe with the variation of content. The lower values of the coercivity indicated the soft ferrimagnetic nature of the synthesized materials. Findings/ Application: Substitution of non-magnetic Cu 2+ ions strongly influenced the structural and magnetic properties of magnesium ferrites.

“…Furthermore, the samples with the addition of Co 2+ and rare earth (La 3+ and Ce 3+ ) cations, dual-phase nanostructures emerge, such as cubic spinel and orthorhombic LaFeO3 with space group (P b n m) for Co-La doped ZCF sample [9] and CeO2 for Co-Ce doped ZCF sample [25]. The existence of this phase is explained by the difference in ionic radii among Zn 2+ (0.82 Å) [26], Cu 2+ (0.70 Å) [27], Co 2+ (0.82 Å) [26], La 3+ (1.06 Å) [9], Ce 3+ (1.02 Å) [25] and Fe 3+ (0.67 Å) [9], with Fe 3+ ions being replaced by La 3+ and Ce 3+ ions in Co-La doped ZCF and Co-Ce doped ZCF samples, respectively and reduced solubility in the Zn-Cu ferrites. After this point, rare earth ions start to accumulate around grain boundaries, forming a secondary phase [25].…”
