The surface tension of molten Sn–Bi (mole fraction XBi=0.455XBi=0.455) alloy has been determined by the sessile drop method at oxygen partial pressure (PO2)(PO2) of 1.0×10−6MPa and different temperatures. The experimental results have been analyzed and discussed, and the positive temperature coefficient of surface tension of molten Sn–Bi alloy has been elucidated. The surface tension of this molten alloy has also been obtained by calculation using STCBE based on Butler's equation and thermodynamic data. The experimental results agree well with the calculation values.
Graphical abstractThe surface tensions of molten Sn–Bi alloy have been measured by sessile drop method, and the data acquirement comes from our self-developed software. The surface tension calculation is based on Butler's equation.Figure optionsDownload full-size imageDownload as PowerPoint slide
