dc.description.abstract | Niobium and aluminium were electrodeposited at 200 °C under argon
atmosphere onto vitreous carbon from inorganic chloroaluminate melts (AlCl3+NaCl)
with added niobium. Niobium was introduced into the electrolyte by anodic dissolution
of metallic niobium or by chemical dissolution of Nb2O5 in a melt of equimolar
AlCl3+NaCl mixture. The processes of deposition/dissolution onto/from vitreous carbon
were investigated by cyclic voltammetry and chronoamperometry. Characterization of
the obtained deposits was done by Scanning Electron Microscopy (SEM) and Energy
Dispersive Spectroscopy (EDS). The only observed reduction processes on the working
electrode in the potential window from 1.000 V to – 1.000 V vs. Al, were individual
niobium deposition and codeposition of niobium and aluminium with Al-Nb alloys
formation.
Electrodeposition of niobium from the chloroaluminate melt with added niobium
(V) oxide seems to start at around – 0.100 V vs. Al and at about – 0.200 V vs. Al
aluminium starts codepositing. During the codeposition Nb-Al alloys were formed.
Niobium deposition starting potential from the electrolyte with niobium added by
anodic dissolution starts at 0.100 V vs. Al, and aluminium codeposition starting
potential was at around – 0.025 V vs. Al, followed by Nb/Al alloy formation. | sr |
