The binary Ag-Sb system shows strong negative deviation from ideality in the Ag-rich side, and a weak positive deviation on the Sb-rich side. Excess thermodynamic properties of this system are assessed in [1-2]. The goal of this work is to calculate the concentration dependence of the surface tension and dynamic viscosity of the Ag-Sb liquid alloy, based on surface tension and viscosity of the pure components and the excess thermodynamic properties of the alloy. The calculated results are compared to experimental data and good agreement is found.
