Preparation and Characterization of Spinal Zinc Ferrite ZnFe2O4 Using the Sol-gel technique

Abstract

Zinc Ferrite ZnFe2O4 powder were prepared using the Sol-Gel technique and characterized by
XRD, FE-SEM, AFM, TGA, and DSC. The X-ray diffraction spectra of spinal Zinc ferrite
ZnFe2O4 that was synthesized using the sol-gel technique. X-ray diffraction (XRD) determined
that ZNF has a cubic structure, and atomic force microscopy (AFM) determined that the
average diameter of spinal Zinc Ferrite is (60.73nm), indicating that the sample has a
nanostructure dimension. The morphological studies of the ZnFe2O4 powder that was obtained
were investigated in terms of FE-SEM studies it can be observed that the sample consisted with
many pores. When the temperature of sintering is at 700 degrees Celsius, The images of the
particles reveal that the sample exhibit a compact arrangement and show a spherical structure,
regular with pores. The results of a thermal analysis determined by thermo-gravimetric analysis
(TGA) and calorimeter differential calorimetry (DSC) have demonstrated the presence of a
crystallization endothermic peak, which indicates that ZnFe2O4 powder is thermally
stable.
