THE MECHANISM AND KINETICS OF SYNTHESIS OF FE4V2MO3O20 PHASE IN THE SOLID-STATE

Studies on the mechanism and kinetics of the reactions taking place in the solid state without mass change, involved in the synthesis of Fe4 V2Mo3O20 have been made using X-ray diffraction (XRD) and infrared spe ctroscopy methods. The XRD study was carried out in a high temperature X-ray attachment. The mechanism of the synthesis process is discussed . The reaction rate constants and apparent activation energies for the distinguishable stages of the synthesis have been calculated, basing on the Erofeev model.
