Abstract
The Cu solubility was measured in the CaO-B 2O 3 and BaO-B 2O 3 slag systems to understand the dissolution mechanism of Cu in the slags. The Cu solubility had a linear relationship with oxygen partial pressure in the CaO-B 2O 3 slag system, which corresponds with previous studies. Also, the Cu solubilities in slag decreased with increasing the slag basicity, which value of slope was close to -0.5 in logarithmic form. From the results of experiment, the Cu dissolution mechanism established as follows: To compensate the effects of oxygen partial pressure and chemical potential of Cu in alloy on the Cu solubility of slag, the concept of cuprous capacity was suggested as follows: The cuprous capacity showed decreasing tendency as the slag basicity increased in the B 2O 3 bearing slags as well as in CaO-SiO 2-Al 2O 3(Satd.) and FeO-Fe 2O 3-SiO 2(Satd.) slag systems. It is suggested that the proposed dissolution mechanism could be available in various slag systems.
