Abstract

This chapter provides the enthalpy of formation of Nb-Si (niobium-silicon) system.

Thermodynamics

Results from high-temperature direct synthesis calorimetry at 1473 ± 2 K have been used by Meschel et al. [98Mes] to calculate standard enthalpies of formation of intermediate phases. The results obtained are given in Table 1.
