Rietveld refinement and structural characterization of powder ZnFe2O4 synthesized through coprecipitation method

This article describes the synthesis of powdered ZnFe2O4 (zinc ferrite) using coprecipitation method. The obtained samples were structurally characterized using XRD (X ray diffraction). The diffraction data of the. prepared samples were refined using full pattern fitting by the Rietveld method. The diffractogram of the samples has shown the formation of cubic spinel structure corresponding to the space group Fd-3m. The wyckoff positions, discrepancy factor and interatomic distance have been calculated. The lower values of profile parameters such as Rb, Rwp, Rexp, χ2 indicated that the calculated diffraction pattern is in fair agreement with observed pattern. Some applications of nanosize zinc ferrite have also been highlighted.This article describes the synthesis of powdered ZnFe2O4 (zinc ferrite) using coprecipitation method.
