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:

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
