In this work, the microstructure and thermal properties of four Ag—Sb alloys with 12.1, 40.0, 43.9 and 81.1 at.% Sb were experimentally studied. The constitutive phases were investigated using scanning electron microscopy (SEM) with the energy dispersive spectroscopy (EDS). The phase transition temperatures of the investigated alloys were determined using differential scanning calorimetry (DSC) and compared with the results obtained by thermodynamic calculation. The measured temperature of the eutectic reaction was 484.1 °C. The measurement of thermal diffusion in the temperature range from 25 to 400 °C was performed using the xenon-flash method, followed by the determination of the thermal conductivity. Temperature and composition dependences of density, thermal diffusivity, specific heat capacity and thermal conductivity for solid Ag-Sb alloys were determined. Thermal conductivity of Ag—Sb alloys shows large negative deviation from a linear rule of mixing. Thermal diffusivity and thermal conductivity are the lowest for the Ag-12.1 at.% Sb alloy and gradually increase with increasing antimony content.
