Abstract

This chapter provides the enthalpy of formation of Rh-Tm (rhodium-thulium) system.

Thermodynamics

Using direct synthesis calorimetry at 1400 ± 2 K Guo et al. [97Guo] have obtained enthalpies of reaction, which have been used, besides others, to calculate the standard enthalpy of formation of intermediate phases. The results are given in Table 1.
