Густина та поверхневий натяг розплавів Sn1–xBix

The surface tension and the density of the Sn1−xBix system with Bi concentrations of 5, 10, and 15 at% have been studied using the lying drop method in a temperature interval of 470–800 K and under a vacuum of 10 Pa. The DROP program is used to obtain experimental values of the studied physical quantities. The addition of bismuth to tin was found to decrease the surface energy of the Sn1−xBix melts. It is also shown that there are linear temperature dependences for the surface tension coefficient and the density of the studied system.
