Structural, Thermal and Chemical Properties of Co-Cr Fe2O4 Nanocomposite Synthesized by Combustion Method

Abstract

Published by Madridge Publishers Abstract Co-Cr Fe2O4 Nanocomposite were synthesized by solution combustion method and synthesized powder were characterized by X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and Thermal Properties (DSC). The XRD results confirm the cubic spinel structure of the ferrites and crystalline size (D) found the range of 40-50nm. The FTIR measurement between 400 – 4000 cm-1confirm the absorption bands in the Spectrum. Further, Thermogravimetric analysis and differential scanning calorimetry were used to investigate the phase transition and melting point of the prepared samples respectively. Agglomeration of particles was observed in the scanning electron microscopy (SEM) images. The results underline the effect of preparation conditions on the morphology, crystallite size, and thermal properties of nano ferrites.
