Iron Oxidation State Analysis in ESR Slag

Abstract:

It is shown that the value of the equilibrium oxygen partial pressure, Po₂ as a value available for measurements is possible to be taken as a measure of slag redox potential of, taking into account its electronic system performance. Application of the electromotive force method (EMF) allowed establishing the character of a change in the average oxidation state of iron ν_Fe depending on Po₂, the temperature and slag composition. The study of Mössbauer absorption spectra of quenched slag samples confirmed the possibility of simultaneous presence of iron in the flux in oxidation states from 0 to +3.
