Abstract

The CaO–SiO2–Sm2O3 system is valuable for Sm2O3 recycling. However, the phase relations in this system have not been systematically studied previously. Therefore, the CaO–SiO2–Sm2O3 slag system was studied at T = 1773 K and T = 1873 K through thermodynamic equilibrium experiments in argon atmosphere. The equilibrated phases were measured by electron probe microanalysis (EPMA) and X-ray diffraction (XRD). At 1773 K, one liquid-phase region, twelve two-phase regions, and nine three-phase regions exist in the CaO–SiO2–Sm2O3 ternary system. At 1873 K, one liquid-phase region, eleven two-phase regions, and nine three-phase regions are presented in the system. The resulting data on the existence of solidus, solid solutions, and liquid regions were used to construct the isothermal sections for the CaO–SiO2–Sm2O3 ternary system. The data from this work will further investigations on the feasibility to recover Rare-earth elements (REEs) through pyrometallurgical processing.
