Abstract

The activity of bismuth in binary dilute solutions shows positive deviation from Raoult's law, and the activity coefficient at infinite dilution is estimated at 2. 6 at 1373 K. The activity of antimony in binary dilute solutions shows negative deviation from Raoult's law and the values are estimated at 2. 0 multiplied by 10** minus **2 at 1373 K, 1. 0 multiplied by 10** minus //2 at 1273 K and 4. 9 multiplied by 10** minus **3 at 1173 K. Activity curves of antimony at various temperatures show a crossover point at about N//S//b equals 0. 3 near the composition corresponding to intermetallic compounds.
