Abstract

The sulfur partition ratio between carbon-saturated iron and Na2O-SiO2 slags and the sulfide capacity of these slags have been measured at 1200 °C. The two measurements are consistent with each other and the results are compared with other investigations. These slags have higher sulfide capacities and partition ratios than equivalent CaO-based slags and are thus attractive desulfurizers. Both the sulfide capacity and the partition ratio increase with increasing Na2O. The activity coefficient of Na2S has been calculated; it also increases with increasing Na2O. The solubility of sulfur in a slag of 0.4 mole fraction Na2O is estimated to be 5 pct.
