Synthesis, Crystal Chemistry and Antistructure Modelling of CoFe2O4 Nanoparticles Prepared by Citrate Sol-Gel Method
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 4
Abstract
Cobalt ferrite nanoparticles were synthesized by the citrate sol-gel method and characterized by XRD, FT-IR, TG-DSC techniques. X-ray analysis confirms the formation of single phase cubic partially inverse spinel structure with the average particle size of 37 nm. Distribution of cations among the two interstitial sites (tetrahedral and octahedral sites) has been estimated by analyzing the powder X-ray diffraction pattern by employing Rietveld refinement technique. The FT-IR study between 4000 and 370 cm-1 shows two absorption bands corresponding to tetrahedral and octahedral sites of CoFe2O4 spinel structure. Crystalloquasichemical model of formation СoO and Fe2O3 defects phases and their interactions was described.
