Electrical resistivity of liquid Sn–Sb alloy

An investigation of the temperature dependence of the electrical resistivity (ρ– T ) of Sn–Sb alloys is carried out, using the DC four-probe method. A clear turning point is observed in some compositions of the Sn–Sb melt, but not at every composition, at which the resistivity–temperature coefficient increases rapidly. The anomalous variation of the resistivity at certain temperatures for the Sn–Sb melt may be due to the remaining covalent and heterogeneous bonds and also the difference in bonding ability between Sn and Sb atoms, which might yield temperature-induced structure changes in some compositions of liquid Sn–Sb alloys. Besides this, analysis of the composition dependence of the resistivity is also included in this paper.
