To explore the reduction process of antimony oxide(Sb2O3)in high-temperature molten lithium chloride, Sb2O3 was reduced to metallic antimony by electrolytic reduction and lithothermal reduction process respectively. The phase structure of products was analyzed by XRD, and electrochemical signals of Sb2O3 powder were accurately measured using molybdenum cavity electrode. Based on thermodynamic analysis and E-pO2-diagrams, it is confirmed that Sb2O3 can be effectively reduced by electrolysis, yielding metallic Sb at potentials below 1.65 V (vs. Li/Li+). With a potential of 0.94 V (vs. Li/Li+) and electrolysis duration of 6 h, the antimony reduction rate can reach 82.0%. The conditions for lithium thermal reduction are as follows:metallic lithium is added at the theoretical dosage, reaction temperature of 923 K, and reaction time of 6 h. And the antimony reduction rate can reach 77.0% under these conditions.

为了探索氧化锑(Sb2O3)在高温氯化锂熔盐中的还原过程,采用电解还原技术和锂热还原法将Sb2O3还原为Sb,并通过XRD对产物结构进行了表征。通过金属钼空腔电极准确测定了氧化锑粉末的电化学信号,结合热力学分析和E-pO2-图,发现Sb2O3可以通过电解的方式被还原,实验中控制电位低于1.65 V(vs. Li/Li+)可以获得金属单质Sb,电位0.94 V(vs. Li/Li+)、电解时间6 h条件下,锑还原率可达82.0%。锂热还原条件为:Li金属加入量为理论用量、反应温度923 K、反应时间6 h,在此条件下,锑还原率可达77.0%。

为了探索氧化锑(Sb2O3)在高温氯化锂熔盐中的还原过程,采用电解还原技术和锂热还原法将Sb2O3还原为Sb,并通过XRD对产物结构进行了表征。通过金属钼空腔电极准确测定了氧化锑粉末的电化学信号,结合热力学分析和E-pO2-图,发现Sb2O3可以通过电解的方式被还原,实验中控制电位低于1.65 V(vs. Li/Li+)可以获得金属单质Sb,电位0.94 V(vs. Li/Li+)、电解时间6 h条件下,锑还原率可达82.0%。锂热还原条件为:Li金属加入量为理论用量、反应温度923 K、反应时间6 h,在此条件下,锑还原率可达77.0%。

To explore the reduction process of antimony oxide(Sb2O3)in high-temperature molten lithium chloride, Sb2O3 was reduced to metallic antimony by electrolytic reduction and lithothermal reduction process respectively. The phase structure of products was analyzed by XRD, and electrochemical signals of Sb2O3 powder were accurately measured using molybdenum cavity electrode. Based on thermodynamic analysis and E-pO2-diagrams, it is confirmed that Sb2O3 can be effectively reduced by electrolysis, yielding metallic Sb at potentials below 1.65 V (vs. Li/Li+). With a potential of 0.94 V (vs. Li/Li+) and electrolysis duration of 6 h, the antimony reduction rate can reach 82.0%. The conditions for lithium thermal reduction are as follows:metallic lithium is added at the theoretical dosage, reaction temperature of 923 K, and reaction time of 6 h. And the antimony reduction rate can reach 77.0% under these conditions.
