Аннотация: Structural features of spinel ferrites formed by rapid quenched from the liquid state, has been studied. It was found that higher quenching rates cause sequential disorder of the spinel structure. Process starts with statistically uniform redistribution of cations at lattice points, then collapse of the anionic frame leads to the topological disorder. This process results in formation of the thermodynamically unstable cluster state and heating of these hardened ferrites leads to a stepwise release of energy. Therefore the described process improves activity of ferrite powders in solid-phase and catalytic reactions. (C) 2015 Elsevier B.V. All rights reserved.
