Abstract

This chapter provides the enthalpy of formation of Nd-Rh (neodymium-rhodium) system.

Thermodynamics

On the basis of results obtained with applying high-temperature direct synthesis calorimetry at 1477 ± 2 K Guo et al. [95Guo] have obtained informations, which have been used to calculate standard enthalpies of formation of intermediate phases. The results are shown in Table 1.
