CO2 absorption characteristics of a blanket candidate material Li2TiO3 under exposure to different gas mixture

In order to investigate the CO2 absorption characteristics of the low- and high-density Li2TiO3 samples, X-ray diffraction (XRD) and non-Rutherford backscattering spectroscopy (NRBS) analyses have been performed. Crystallographic structure of a sintered sample is decided by the XRD analysis, and the NRBS analysis has evaluated the amount of CO2 absorption quantitatively. The amount of CO2 absorption of the low-density Li2TiO3 samples is increased with increase of the humidity. We find that the humidity has effect on CO2 absorption to the low-density Li2TiO3 samples. On the other hand, the high-density samples sintered at temperatures higher than 1,470 K absorb very little CO2 under high humidity conditions.
