Thermodynamic properties of Sn-Tm (tin-thulium) system
This chapter provides the enthalpy of formation and crystal structure of Sn3Tm5.
The structure of the intermediate phase Sn3Tm5 is hexagonal (Mn5Si3 – type). Meschel et al. [99Mes] succeeded in determining its standard enthalpy of formation. They found the value
ΔHS298 = − 72.8 ± 2.1 kJ g-atom−1.
