ResumoThe aging in air of a cubic sample of samarium sesquioxide has been studied by TPD and X-ray Diffraction. Though the hydration and carbonation of the oxide occur in bulk, when the apparent stabilization of the sample is reached, the starting phase is only partially transformed. The thermal evolution of the aged in air sample, as deduced from IR Spectroscopy and X-ray Diffraction studies, suggests that an hydroxycarbonate phase as well as samarium hydroxide are formed when this samaria sample is exposed to the air.
