Abstract  Measurements of the surface tension of the Pb-Sb binary melts were made by the sessile drop method. All the temperature coefficient of their surface tension was obtained in a negative quantity. At the same measuring temperature, the values of the surface tension of Pb-Sb melts lie between that of each pure component and vary non-linearly with their compositions which show a negative diviation from the "ideal solution". As the results of this liquid binary eutectic alloy, a concept of the "liquid similar eutectic atomic clusters" (LSEAC) may be approached by the authors to interpret the surface tension phenomena of the binary alloys of eutectic type.
