Query: Entropic Stabilization and Retrograde Solubility in Zn4Sb3   Zn4Sb3 is shown to be entropically stabilized versus decomposition to Zn and
ZnSb though the effects of configurational disorder and phonon free energy.
Single phase stability is predicted for a range of compositions and
temperatures. Retrograde solubility of Zn is predicted on the two-phase
boundary region between Zn4Sb3 and Zn. The complex temperature dependent
solubility can be used to explain the variety of nanoparticle formation
observed in the system: formation of ZnSb on the Sb rich side, Zn on the far Zn
rich side and nano-void formation due to Zn precipitates being reabsorbed at
lower temperatures.
