Peculiarities of wustite formed below 570 °C

Abstract

By means of the Mössbauer effect, the wustite formed during the reduction process of hematite below 570 °C has been studied. The main Mössbauer parameters of stoichiometric wustite have been obtained for the paramagnetic and antiferromagnetic regions. The hematite reduction is shown to proceed through the stoichiometric wustite at temperatures up to 425 °C.
