Abstract

The article presents the results of experimental studies on concentration and temperature dependence of surface tension (ST) and density of indium-tin alloys. The characteristic feature of these experiments is that we studied surface tension and density by two independent methods that improved reliability of data and allowed us to solve some problems. In particular, experimental data on ST received by both methods proved that SF concentration dependence has a shallow minimum, which exceeds the limits of experimental uncertainty, in the area of average compositions. With an increase in temperature, the extremum depth decreases and when temperature is higher 773 К the minimum almost vanishes. It proves that isotherms ? of ideal solutions can be characterized by these minimums if pure components (indium and tin in this case) have similar values of physic-chemical properties. The experiments showed that within temperature ranges from the melting point to 773 К the surface tension and density of pure metals (indium and tin) and binary-based alloys are linearly dependent on temperature. Experimental data on density received by two methods (aerometric and a big drop method) evidence that alloys density values coincide with additive values within experimental uncertainty. Curves show concentration dependence of molar volumes. They have slight positive deviations from the additive straight line.
