Abstract

This chapter provides the entropy of formation of Rh-Tb (rhodium-terbium) system.

Thermodynamics

Applying direct synthesis calorimetry and from average heat content at 1474 ± 2 K Guo et al. [95Guo] have calculated the standard enthalpies of formation of two intermediate phases. The results are given in Table 1.
