Description :
Magnesium ferrite MgFe2O4 synthesized by oxalate co-precipitation method using high purity sulphates. The synthesized powder is characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared radiation (FTIR) technique. The sample were sintered at different temp 4000C, 5000C, 6000C for 5hr. The X-ray diffraction analysis conforms the formation of single phase cubic spinal structure of the sample. The Lattice constant, X-ray density, physical density, porosity, crystallite size, site radii (rA, rB) Bond length (A-O, B-O) were calculated. The grain size increase with temperature. The FTIR spectra show two strong absorption bands around the range of 350cm-1 and 800cm-1 to tetrahedral and octahedral respectively.
Keywords: Synthesis; crystallite size; XRD; Grain Size.
