Measurement of Surface Tension of Liquid Ga Base Alloys by a Sessile Drop Method

The surface tensions and the molar volumes of liquid GaBi, Ga-Sn, Ga-In, Sn-Bi, In-Bi and Sn-In binary alloys, and liquid Ga-Bi-Sn and Ga-Bi-In ternary alloys have been measured at 873 K by the sessile drop method. In addition, the calculation of the surface tension of the above binary alloys has been carried out to interpret the composition dependences of the surface tension of Ga-base liquid alloys from the thermodynamic point of view.
