Abstract
Electrochemical behavior of niobium in the melt CsCl-KCl-NaCl-NaF (10 wt%)-K2NbF7 is studied on vitreous-carbon electrode by the linear volt ammetry technique. Investigations at temperatures ranging from 973 to 1073 K show that the cathode process of discharging NbF72- complexes i ncludes a reversible step of recharging the pentavalent niobium to the tetravalent state and a subsequent irreversible step of discharging t he tetravalent niobium to metal. Kinetic parameters of both steps are determined.
