| Abstract: | 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 ofSb were calculated from the obtained data and those of Cu by Gibbs-Duhem inter-gration. Problems about the experimental techniques have also been discussed. |
