Abstract Scope |
The electrodeposition of critical base metals and rare earth metals using a eutectic mixture of urea and choline chloride (IL) was discussed. The maximum current efficiencies obtained for Co, Zn, Pb and Cu were 95%, 91.3%, 96.4 % and 97%. The deposition of alloys of zinc like Zn-Sn, Zn-Cu, Zn-Ni, Zn-Mn and alloys of nickel like Ni-Mn, and Fe-Co-Ni were reported. The co-deposition of rare earth elements like Co-Nd and Sm-Co alloy were also carried out, because of rare earth metals cannot be deposited alone in urea melt due to their high negative reduction potentials of the rare earth ions. The effect of Urea and choline chloride or EMIC or BMIC on the electrodeposition of critical base metals and rare earth elements was discussed. The critical parameters in the electrodeposition processes were identified, such as current density and efficiency in metals and alloys production |
