Formation enthalpies of various ternary intermetallic compounds in the Cu-Li-Sn system

Five intermetallic Cu-Li-Sn compounds have been synthesized by induction melting and annealing. Their phase purity was checked by powder X-ray diffraction. Enthalpies of solution of compounds in lithium or tin at 873 K were determined by drop calorimetry and extrapolated to limiting enthalpies of so...

Summary:Five intermetallic Cu-Li-Sn compounds have been synthesized by induction melting and annealing. Their phase purity was checked by powder X-ray diffraction. Enthalpies of solution of compounds in lithium or tin at 873 K were determined by drop calorimetry and extrapolated to limiting enthalpies of solution. The limiting enthalpies of solution of copper in lithium and lithium in tin at 873 K were measured in the same way. Enthalpies of formation of the ternary compounds were calculated according to Hess' law and compared with enthalpies of mixing in the liquid. An analogy between formation enthalpies and mixing enthalpies was found.
