[en] LiCl-LiF-GdF₃, LiF-GdF₃ and LiF-BaF₂-GdF₃ salts were evaluated for the electrolytic purification of gadolinium. The sum total of the metallic impurities in the final product was found to be less than 50 wt. ppm; less than 100 wt. ppm each of the interstitial elements H, C, N, O and F was present. LiF-GdF₃ yielded the highest purity gadolinium metal with respect to oxygen, even though this electrolyte and its deposits were handled in air. Metallographic and chemical analyses demonstrated that the extraction of fluoride inclusions from the metal was best achieved by electron beam melting. (Auth.)
