摘要：
The present work aimed to measure the thermodynamic data of manganese in Cu-Mn melts over a broad manganese concentration range, using the equilibrium among the liquid copper/MnO(s)/CO-CO2 gas mixture in the temperature range from 1673 K to 1873 K (1400 A degrees C to 1600 A degrees C). Darken's quadratic formalism was introduced to correlate the activity coefficient of manganese in copper to composition, and the excess molar Gibbs energy change of mixing of Cu-Mn melts was described satisfactorily by Redlich-Kister type polynomial.
