Abstract The results of a comprehensive study of the electronic and crystal structure of cobalt ferrite alloys (CoFe2O4) synthesized by solar melting are presented. Using X-ray phase analysis and the Rietveld refinement method, the crystal lattice parameters were determined and secondary phases of CoO and Fe2O3 were identified. Electron density mapping was performed, which allowed us to establish the nature of the Co–O and Fe–O bonds, as well as to identify the covalent component in the crystal lattice. The data obtained indicate the influence of CoFe2O4 composition on the symmetry, phase purity, and electron density distribution.
