• Deoxidation and desulfurization equilibria of liquid iron, as influenced by neodymium, were investigated at a temperature of 1 873 K. The following thermodynamic values for neodymium deoxidation and desulfurization were derived:<center><a href="http://ess.jstage.jst.go.jp/preview/article/isijinternational/49/11/49_1656/_appendix/1">[Equation]</a></center>Using the thermodynamic data derived in this study, deoxidation and desulfurization equilibria of liquid iron by neodymium are presented for the Fe–Nd–O–S system. Moreover, the interaction parameter, Al for Nd (eNdAL) was determined to be 4.9(±4.1) at 1 873 K.
