The effect of small additions of co on the density and surface properties of liquid tin

Abstract

Density and surface tension of the molten Sn-Co containing 2.5; 5 and 10 at% of Co have been studied by means of sessile drop method. The temperature dependence of obtained parameters is analyzed and interpreted from the viewpoint of cluster structure. It is shown that the density and the surface tension reveal an anomalous behavior due to the formation of chemically ordered clusters on the surface and in the bulk melt.
