The distribution ratio of antimony between Na2CO3-slag and molten copper at temperatures of 1423, 1473, and 1523 K has been measured by using a sampling technique in a pure argon atmosphere, and determined as a function of oxygen pressure of the alloy. On the basis of distribution results, predominant dissolved species of antimony in Na2CO3-slag has been suggested to be pentavalent in the oxygen pressure range of 10−3∼10−1 Pa. Furthermore, the effect of CO2 pressure on the antimony distribution has been estimated with the aid of activity data for Na2O-CO2-Sb2O5 melt. These results are compared with other investigations.
