Effect of Fe<sup>2+</sup>/Fe<sup>3+</sup> Ratio on the Reduction Behavior of SFCA-I in Hydrogen-enriched Atmosphere
In this study, the influence of Fe2+/Fe3+ ratios in SFCA-I on its reducibility are examined. Five types of powder samples containing SFCA-I with different Fe2+/Fe3+ ratios were prepared using chemical reagents by solid phase reaction at high temperature. The samples were heated up to 800°C in the different atmospheres of CO–CO2–H2–H2O systems. The reducibility of the samples was evaluated using the integrated intensity ratio identified by XRD before and during the reduction experiment.
