Fig. 8.11 The gold-silicon phase diagram The melting temperatures of gold and silicon are 1063oC and 1404oC, respectively, and the enthalpies of fusion are 12.8 and 50.6 kJ/mole, respectively.

In the Au+L two-phase region, pure solid gold is in equilibrium with a liquid phase with compositions along the Au-rich liquidus. Equating the chemical potentials of these two phases as expressed by Eq (8.3) gives:

where xAu,L is the mole fraction of gold along the Au-rich liquidus. using the terminology of Eqs(8.13) and (8.14), Eq (8.28) can be solved for Yau,l:

M,Au
