Thermodynamic properties of NaO0.5-CO2–XOv/2 slag (X: P or Si, v: valence of X) have been investigated by conducting the following measurements: (1) Solubility measurements of Na3PO4 (s) into sodium carbonate melts at 1423 to 1523 K under various partial pressures of CO2 and oxygen. (2) Activity measurements of NaO0.5 under various partial pressures of CO2. (3) Solubility measurements of CO2 in the slags. Based on the results, the equilibrium distribution ratios of P and Si between the slags and the molten copper have been estimated as a function of partial pressures of CO2 and oxygen and the slag composition at 1523 K.
