Equilibrium Between FeO - MnO Slags and Iron-Manganese Alloys

Abstract

This dissertation describes the determination of the equilibrium constant for the reduction of ferrous oxide by manganese to yield manganese oxide and iron. The experimental work was carried out over the temperature range of 1650°C to 1870°C. The results from the present work were combined with reliable published data to give what is considered to be the best relationship between the equilibrium constant and the temperature. The difference between this study and previous work on this topic is the radically new experimental approach. While previous workers used crucible techniques to achieve equilibrium for their system and standard wet chemical analysis, the method used here involved levitation melting and analysis by the electron probe micro-analyser.
