Abstract:

Magnesium ferrites are the potential materials for various applications due to their high electrical resistive. Many physical properties of MgFe2O4 depend on their microstructure, porosity, grain size, state of chemical order and the cation distribution [1-2]. The main objective of this study was to synthesize and characterization of MgFe2O4 using MgCl2 and FeCl3 at 900˚C for 10 h by solid state reaction. The employed techniques are XRD, SEM and FT-IR. XRD pattern of powdered sample of MgFe2O4 is presentedin Fig.1. The XRD pattern provides information about single-phase formation of spinel structure with cubic symmetry. The crystallite size of MgFe2O4 sample was calculated from x-ray lines broadening of the reflections of (220), (311), (222), (400), (442), (511), (440), (533) and (444) using Scherrer’s equation (D=31 nm). Also, the formation of spinel MgFe2O4 structure was further supported by FT-IR spectra (Fig.2). Fig.3 shows the FESEM image of sample. It shows that there are some multigonal structures including the triangle prism morphology. The optical properties of the obtained material showed that the material has strong absorption in UV light region. Direct optical band gap energy of the obtained material was 2.7eV.
