From: Miscibility and ordered structures of MgO-ZnO alloys under high pressure
Calculated enthalpies as the function of pressure.
(a) Enthalpy curves (relative to I4/mmm phase) for Pm-3m MgZn3O4, (b) Enthalpy curves (relative to I41/amd phase) for P4/mmm MgZnO2, (c) Enthalpy curves (relative to Immm phase) for Cmcm Mg2ZnO3 and (d) Enthalpy curves (relative to I4/mmm phase) for Pm-3m Mg3ZnO4 by CASTEP code. The values in brackets represent the pressures at which MgZn3O4, MgZnO2 and Mg3ZnO4 become stable against decomposition into B3-ZnO and other oxides (MgxZn1−xO, or B1-MgO).
