Abstract

Abstract

A cyclic vollammelry is emploied to determine the amount of oxide in FLTNAK melt. K₂NbF₇ is a good litrant. The amount of oxide is also determined by a vollammetric standard addition method. The results show that the amount of oxide in FLINAK melt is equal to the added amount of Nb(V) minus the amount of NbF₇^2- in the melt.
