Experimental Study and Thermodynamic Modeling of Phase Equilibria in BaO-Fe₂O₃ System

Abstract:

This paper presents the results of the synthesis of compounds of BaO-Fe₂O₃ system and the results of the study of nature and the melting temperatures of the resulting compounds. Based on the analysis of published data, as well as the results of our studies the systematization of information on the BaO-Fe₂O₃ system was conducted and an updated phase diagram of this system was proposed.
