Formation kinetics of Sr2FeMoO6 double perovskite

The formation kinetics of Sr2FeMoO6 (SFMO) was diagnosed during the solid-state reaction of SrFeO3 - x and SrMoO4 at different temperatures and heating rates. The reaction kinetics was analyzed by X-ray diffractometer, and the extent of the reaction was quantified by the internal standard method. The non-isothermal kinetic empirical model was proposed to evaluate the activation energy and rate constant of SFMO and further justified to be valid to picture the reaction kinetics of SFMO.
