Abstract

Electroreduction of niobium is studied in a chloride-fluoride electrolyte used for obtaining zirconium powder. Limiting densities of cathodic diffusion currents of the niobium discharge and diffusion coefficients for fluoride complexes of Nb(V) and Nb(IV) are determined as functions of temperature. Optimum electrolysis parameters are determined by studying how the cathodic current density, niobium concentration, and temperature affect the cathodic electrodeposition current efficiency. The morphology and granulometric composition of powdered niobium are investigated as functions of the electrolysis parameters. Effect of zirconium, as a melt component, on the electrolytic niobium production is discussed
