Mixed zinc substituted magnesium ferrites having the chemical formula Mg1-xZnxFe2O4 (where x = 0.4, 0.5 and 0.6) were synthesized by co-precipitation method using oxalate precursors. The studies of x-ray diffraction, scanning electron microscopy and energy dispersive x-ray spectroscopy were confirmed the crystal structure, phase formation and morphology of sintered spinel ferrite.XRD study reveals that the completion of the lattice formation without any impurity phases. The crystallite size is found to be in 39.17 nm to 21.29 nm range. The lattice parameter (a) was found to increase linearly with Zn2+ content (x). Scanning electron micrographs revealed that an increase in the grain size (D) with increase in Zn2+ content. EDAX shows the presence of Mg2+, Zn2+, Fe3+ and O2− ions as per the stoichiometry. Lattice parameter, x−ray density, the unit cells volume and the hopping lengths for octahedral (LB) and tetrahedral (LA) sites were calculated. |
