Electrochemical studies of rare earths in fluoride melts

摘要

Liquid electrochemical methods were used to generate the cyclic voltammograms of Sm(III),Yb(III) and Eu(III) in glass forming fluorozirconate and fluoroaluminate liquids. All three species were observed to undergo reduction within the window of stability of the liquids. In all cases we hypothesized that it is the M(II) state that is generated. The redox processes observed were found to be close to reversible at smaller scan rates, becoming quasi-reversible at larger scan rates.
