| Abstract Scope |
In this study, the production of samarium metal through the reduction of samarium oxide using calcium as a reductant was systematically investigated. Thermodynamic modeling, based on Gibbs energy minimization, was employed to calculate theoretical yields and the mole percentage of samarium in the Sm-Ca alloy. The study examined the effect of temperature (800, 1000, 1200 °C) and calcium mole fraction (0.50–0.89) on samarium yield and samarium mol% in the Sm-Ca alloy. The results show that samarium yield decreases with increasing temperature but improves significantly with higher calcium mole fractions. Simultaneously, samarium mol% in the alloy tends to decrease as excess calcium is introduced. The calculated results were also compared with literature data to evaluate and report the observed trends. |
