## Description

- description: In this study, the solubilities of oxygen in molten Sm -La-O alloys
    were measured and the oxide phases in quilibrium with the alloys were identified
    at temperatures between 1473 –1673 K. Sm2O3 oxide pellets and Sm-La-O alloy were
    annealed at a fixed temperature, at which the alloy phase was maintained as liquid.
    Then the samples were quenched by dropping into cooling water. The oxygen concentration
    in the quenched alloy phase was measured using inert gas fusion infrared absorption
    spectroscopy. The oxygen solubility increased with the increase in temperature
    and the composition of Sm. The composition and crysta l structure of the oxide
    region of the quenched samples were analyzed using SEM-EDS and XRD, resulting
    in A or B type (La, Sm) 2O3 stably existed at high temperatures with molten alloy.
    Larger values in Sm/(Sm+La) ratio was identified in the oxide phase than the Sm-La-O
    alloy phase.
