Structural morphological and infrared properties of Cd2+ substitutes nickel ferrite particles

Abstract

The Structural properties of cadmium substituted nickel ferrite with general formula Ni1-xCdxFe2O4 (x=0.0, 0.1, 0.2, 0.3, 0.4 and 0.5) were synthesized by using Sol-gel auto combustion method. All the chemicals used for preparations was high purity (99.9% Sigma-Aldrich).The prepared nanoparticles samples were investigated by characterizing them through X-ray diffraction, scanning electron microscopy and infrared spectroscopy. From XRD results, it is observed prepared samples were in the nano size having cubic spinel structure with single phase. Lattice constant is found increasing with Cd2+ concentration. The average grain size obtained from SEM in the range of 45-58 nm. The EDAX plot gives the evidence of presence of Ni2+, Cd2+, Fe3+, and O2- ions with proper ratio confirming the desired stoichiometric composition. IR spectra exhibit two distinct absorption bands hear about 400 cm-1 and 600 cm-1
