Polytherms of the density and surface tension of lead alloys with small additions of sodium in the heating mode from temperatures of melting of Pb–Na alloys up to 650°C in an atmosphere of pure He of grade A (99.995%) are studied using the large sessile drop approach. It is found that the density and surface tension fall as the temperature rises, and raising the content of sodium in the studied alloys to 4 wt % leads to a a substantial drop in surface tension.
