VAPOUR PRESSURE OF Sb AND ACTIVITIES IN LIQUID Cu-Sb ALLOYS
蒸气压法测定Cu-Sb合金的活度

The vapour pressure of Sb in liquid Cu-Sb alloys (x_(sb)=0.262--0.815) were measured at 820--1060K by means of torsion effusion method. Activities of Sb were calculated from the obtained data and those of Cu by Gibbs-Duhem inter- gration. Problems about the experimental techniques have also been discussed.
