Synthesis of Spinel MgFe2O4 Ferrite Material and Studying its Structural and Morphological Properties Using Solid State Method

Abstract

Abstract:MgFe 2 O 4 ferrite has excellent magnetic behavior and high resistive material. The properties of Mg ferrite were investigated by solid state reaction method. In this work, our aim is to synthesize MgFe 2 O 4 using oxide precursors (i.e. MgO and Fe 2 O 3 ). The samples were pre-calcined at 800 o C for 5 hours and calcined at 1000 o C for 6 hours and have the single phase cubic spinel structure. The phase composition, micro-morphology, elemental analysis and Wyckoff sites of the products of Mg-Fe-O system were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and Fourier transform infrared (FTIR), respectively. Spinel Mg ferrite belongs to Fd-3m space group. From the XRD result the crystallite size, lattice constant and cell volume of MgFe 2 O 4 was found to be 44.94 nm, 8.426Å and 598, respectively. From SEM result the magnesium ferrite particle size formed was ranged from 251 nm to 414 nm in diameter for the given alcinations temperature at 1000 °C. The EDS spectra confirm the presence of Fe, Mg and O in the compound. In FT-IR analysis vibrations of ions in the crystal lattice of Mg ferrite observed in the range of 1200-400 cm -1 and the high-frequency band (ν 1 ) lies in the 650-530 cm -1 range and the low-frequency band (ν 2 ) in the 446-400 cm -1 range.
