| Abstract | New phase diagram data and a thermodynamic assessment of the Gd2O3-CoO system using the CALPHAD approach are presented, giving liquidus data and mutual solid solubilities of Co in Gd2O3 and Gd in CoO. The thermodynamic model parameters for the ternary Gd Co perovskite phase and for the mutual solid solubilities of Co in Gd2O3 and Gd in CoO are optimized to reproduce these new experimental data, as well as phase diagram data from literature. The Gd2O3-CoO phase diagram is refined based on the results of experiments using combined differential thermal analysis and thermogravimetry, scanning electron microscopy and X-ray diffraction techniques.
