Activity measurements of Na2O in the system Na2O-Fe2O3 have been made by EMF method using sodium beta-alumina as a solid electrolyte between 850 and 1500K. The cell employed in this study was written as;From the determined values of Na2O activity, the values of the standard free energy change for the formation of Na3Fe5O9 and Na2Fe2O4 from pure solid Na2O and Fe2O3 were also calculated as;
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
