A thermodynamic investigation of the Li–Sb system

Many standard thermodynamic data in the binary system Li–Sb can be found in literature; however, they are often derived from electrochemical measurements taken at higher temperatures. The uncertainties associated with the extrapolation of these high-temperature data to room temperature are, however,...

Summary:Many standard thermodynamic data in the binary system Li–Sb can be found in literature; however, they are often derived from electrochemical measurements taken at higher temperatures. The uncertainties associated with the extrapolation of these high-temperature data to room temperature are, however, inherently large. Therefore, a comprehensive investigation of the thermodynamic properties in the Li–Sb system was conducted in this work to generate more reliable data. Four different experimental techniques were used for the investigations. The heat capacities for both binary compounds, Li 2 Sb and Li 3 Sb, were measured for the very first time. In addition, the enthalpies of formation for both compounds were determined by drop solution and direct reaction calorimetry. Furthermore, Knudsen effusion mass spectrometry was performed to measure partial enthalpies and activities of Sb.
