In this study, the production of samariumSamarium metal through the reductionReduction of samariumSamarium oxide using calcium as a reductant was systematically investigated. ThermodynamicThermodynamic modeling, based on Gibbs energy minimization, was employed to calculate theoretical yields and the mole percentage of samariumSamarium in the Sm-Ca alloy. The study examined the effect of temperatureTemperature (800, 1000, 1200 °C) and calcium mole fraction (0.50–0.89) on samariumSamarium yield and samariumSamarium mol% in the Sm-Ca alloy. The results show that samariumSamarium yield decreases with increasing temperatureTemperature but improves significantly with higher calcium mole fractions. Simultaneously, samariumSamarium 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.

摘要

In this study, the production of samariumSamarium metal through the reductionReduction of samariumSamarium oxide using calcium as a reductant was systematically investigated. ThermodynamicThermodynamic modeling, based on Gibbs energy minimization, was employed to calculate theoretical yields and the mole percentage of samariumSamarium in the Sm-Ca alloy. The study examined the effect of temperatureTemperature (800, 1000, 1200 °C) and calcium mole fraction (0.50–0.89) on samariumSamarium yield and samariumSamarium mol% in the Sm-Ca alloy. The results show that samariumSamarium yield decreases with increasing temperatureTemperature but improves significantly with higher calcium mole fractions. Simultaneously, samariumSamarium 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.
