Evaluation of the thermodynamic properties of mixing of the bismuth-antinomy system

Abstract

Although it is known that there is complete miscibility in both the solid and liquid phases in the bismuth-antimony system, there is some uncertainty in the solidus line . The results of GLAZOV obtained by equilibration and quenching, and of CAMPBELL give values about 20 K higher than the compilation of HANSEN, and GLAZOV concludes that precise solidus data are difficult to obtain by quenching. In view of these uncertainties, the additional information available from heats of mixing in the liquid state has been combined with HANSEN's phase diagram to evaluate the thermodynamic properties of the system
