Synthesis and Study of Calcination Effect of Zinc Ferrite on the Structure and Morphology of Nanoparticles

Three samples of spinel powdered zinc ferrites were successfully fabricated via microwave-assisted combustion method followed by calcination at temperature of 500oC for three hours. Phase purity and surface morphology that estimated via XRD pattern and field emission-scanning electron microscopy images (FE-SEM) showed that the samples have cubic spinel - structure with average crystallite size is increase from 15.8 nm to 26.53 nm and from (23.03nm to 28.16 nm when glycine–to-nitrate ratio is decreased before and after calcination at 500 oC for three hours. However the calcination results is increase in average crystallite size and average lattice constant. FE-SEM image indicated that the particles Zinc ferrite possesses shape symmetry and uniformity. Fourier transform infrared spectroscopy (FT-IR) were us to study vibration mode in synthesized spinel ferrite. As calcination the absorption band of a specific bonds are shifted to a lower wavenumber. (paper)
