Nb（V）在FLINAK熔盐中的暂态电极过程

Transient Electrochemical Process of Nb(V) in FLINAK Melt

采用记时电流法和记时电位法对５价铌Ｎｂ（Ｖ）在ＦＬＩＮＡＫ熔盐中的氧化－还原过程进行了研究。结果表明，Ｎｂ（Ｖ）（Ｋ２ＮｂＦ７）在ＦＬＩＮＡＫ熔盐中的电化学还原经历一个电化学－化学－电化学反应（ＥＣＥ）途径。Ｎｂ（Ｖ）在ＦＬＩＮＡＫ熔盐中的还原反应是单电子和４电子两步电化学反应过程。

The redox process of Nb(V) in (K_2NbF_2) in FLINAK melt has been by studied using chronopotentiometry and chronoamperometry. The results show that the electrochemical reduction of Nb(V) in FLINAK melt goes through an electrochemical-chemical - electrochemieal reaction(ECE) process. The electrochemical reaction of Nb (V)in FLINAK melt is a mono-electron and four-electron transfer process.
