Abstract
Activity coefficients of oxygen in sulfide-rich and metal-rich melts in the copper-sulfur system were determined at 1423 and 1523 K by means of a modified coulometric titration technique using the following cell: O (in Cu-S melts) |ZrO2(+CaO)| air, Pt. The activity coefficient values increase rapidly with sulfur composition in the vicinity ofx s = 0.3333. The data obtained for the matte saturated with the metal-rich melts are in good agreement with those obtained by Kuxmann and Benecke and Schmiedl. Those obtained for the metal-rich melts are in good agreement with the results of Sano and Sakao.
