Abstract

This chapter provides the enthalpy of formation of Ru-Tb (ruthenium-terbium) system.

Thermodynamics

Guo et al. [95Guo] have determined the standard enthalpy of formation of two intermediate phases Ru2Tb5 and Ru2Tb with applying high-temperature calorimetry at 1474 ± 2 K. The results are given in Table 1.
