The Electrolytic Removal of Aluminum from a Two-Phase Aluminum-Trialuminum Nickelide Matrix.

Abstract

The selective electrolytic removal of aluminum from a two-phase matrix of aluminum containing an aligned microstructure of a eutectic alloy, Al3Ni, has been demonstrated feasible in aluminum chloride containing molten salts. Both the 1:1 molar ratio aluminum chloride-sodium chloride melt at 175 C and the 2:1 aluminum chloride-1-ethylpyridinium bromide melt at 23 C were found suitable for this separation. The anodic decomposition potential of Al3Ni in these melts was estimated using linear sweep voltammetry. An apparatus of novel design was used to provide a continuously flowing electrolyte stream past the matrix sample effecting an efficient removal of aluminum. (Author)
