Synthesis and characterization of ceria doped zinc ferrite nanopowdered crystallites

Abstract

Abstract In this paper, we have reported the synthesis of fine crystallites of ceria doped zinc ferrite by co-precipitation and an open air heat treatment method. X-ray diffraction (XRD) gave the data for structural analysis. The XRD data were refined by Rietveld refinement using FullProf suite software. The evolution of the crystalline phases has been analyzed. The effect of precursor concentration is reflected in the resulting diffractogram. Structural characterization revealed the cubic structure of zinc ferrite with a space group of FD-3m(227) and the cubic structure of CeO with a space group of fm-3m(225). Structural parameters such as the lattice constant of the direct lattice, the lattice constant of the reciprocating lattice, lattice strain, covalent bond angle, dislocation density, crystallite size and Wyckoff positions were calculated.
