摘要：
The thermal analysis of the oxide–chloride systems GdCl3–Gd2O3 and GdCl3–KCl–Gd2O3 with the Gd2O3 content up to 0.09 mol fractions was studied in the temperature range 298–1173 K using two methods: differential scanning calorimetry and the method of cooling curves. The liquidus temperatures in these systems have been determined. The solubility of the oxide and the thermodynamic characteristics of the dissolution process were calculated. It was established experimentally that the dissolution of Gd2O3 proceeds by a chemical mechanism, with the formation of GdOCl oxychloride. The received data revealed the main regularities of Gd2O3 solubility in molten GdCl3–KCl–Gd2O3 systems.
