Study of Structural Properties of Co1+xZrxFe2-2xO4 Spinel Ferrite

Abstract

Nanocrystalline Co1+xZrxFe2-2xO4 with different compositions with x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5 and x = 0.6 were efficiently prepared by sol-gel self-combustion. Citric acid served as fuel and metal nitrates were AR grade. X-ray diffraction results showed that a single-phase cubic spinel structure was produced. The crystallite size, lattice constant, and X-ray density are all within the above limits. The crystallite size supports the nanocrystallinity of the material. Porosity increases because the bulk density is much lower than the X-ray density. The cation distribution results indicate that the cobalt ferrite sample has an inverse spinel structure, with Zr4+ ions occupying [B] positions exclusively and Co2+ and Fe3+ ions occupying tetrahedral (A) and octahedral [B] positions, respectively. indicates possession.
