摘要
The oxygen activities in the Cu-RE-O melts containing different amount of cerium or mischmetal have been measured by galvanic cell with solid electrolyte in the temperature range from 1440 to 1573 K. The rare earth dissolved in the melts has been determined by ICP-AES (inductively coupled plasma) after the quenched samples were electrolyzed in an organic electrolyte at low temperature (&le20°C) for separating the inclusions. A series of thermodynamic calculation have been done by using the experimental results.
