Experimental Investigation and Thermodynamic Modeling of the Zr O sub(2)- M g O System

The ZrO sub(2)-MgO phase diagram is experimentally studied using XRD, SEM-EDX, and DTA. The ZrO sub(2)-based solutions are modeled as ionic solutions using compound energy formalism. The thermodynamic parameters are optimized using own and literature experimental data. The calculated ZrO sub(2)-MgO...

More Information
Summary:The ZrO sub(2)-MgO phase diagram is experimentally studied using XRD, SEM-EDX, and DTA. The ZrO sub(2)-based solutions are modeled as ionic solutions using compound energy formalism. The thermodynamic parameters are optimized using own and literature experimental data. The calculated ZrO sub(2)-MgO phase diagram is used to interpret the microstructure and phase transformations observed in the industrial Mg-PSZ material in as-received and heat treated states.
