The chlorination of Sm2O3 in the presence of carbon using the gaseous mixture Cl2(g) + Ar(g) has been studied by thermogravimetry. The effects of both the temperature between 200 and 950 ◦C and the total gas flow rate between 2.1 and 7.9 l h−1 on the reaction rate were analyzed. The starting temperature of reaction, the stoichiometry and kinetic regimes of the reaction were obtained. Reactants and products were analyzed by X-ray diffraction (XRD) and electronic dispersive spectroscopy (EDS). The temporal evolution of the solid microstructurewas followed by scanning electron microscopy (SEM).2O3 in the presence of carbon using the gaseous mixture Cl2(g) + Ar(g) has been studied by thermogravimetry.
