PREPARATION AND CHARACTERIZATION OF COPPER SUBSTITUTED MAGNESIUM-ZINC FERRITES
Abstract
- A series of Copper substituted Magnesium-Zinc ferrites, Mg0.5Zn0.5-xCuxFe2O4 (where x = 0.0 – 0.5 with the step of 0.1) were prepared by solid state reaction method. Stoichiometric compositions of MgO, ZnO, CuO and Fe2O3 were used. XRD patterns indicated that the samples were cubic structure and the crystallite sizes were estimated by using the observed XRD spectral lines. Microstructural properties of the samples were investigated by Scanning Electron Microscope (SEM). It was found that the grain sizes of the samples depend on the concentration of Cu. Some pores were found in the observed SEM images. Vibrational characteristics of the samples were investigated by Fourier Transform Infrared (FTIR) spectroscopic method. The collected spectral lines were identified by using molecular vibrational theory and standard data (wavenumbers). The observed wavenumbers showed that the stretching vibrations of tetrahedral site atoms (ȣ1-mode) and octahedral site atoms (ȣ2-mode) that composed of the samples.
