THE phase diagram for the system, ZrO 2 –MgO, was re-investigated by means of the quenching technique and a ribbon element diffractometer furnace. Duwez et al. 1 had first established a tentative phase diagram for this system. Recently, Hinz and Dietzel 2 tried to determine the phase ...
The ZrO2–MgO phase diagram is experimentally studied using XRD, SEM-EDX, and DTA. The ZrO2-based solutions are modeled as ionic solutions using compound energy formalism. The thermodynamic parameters are optimized using own and literature experimental data. The calculated ZrO2–MgO phase diagram is...
