Abstract

This chapter provides the enthalpy of formation of Rh-Y (rhodium-yttrium) system.

Thermodynamics

From enthalpy of reaction of intermediate phases determined by high-temperature calorimetry at 1473 ± 2 K Selhaoui et al. [93Sel] have calculated standard enthalpies of formation. The results are given in Table 1.
