ELECTROCHEMISTRY OF MOLTEN SALT ENHANCED CARBOTHERMIC REDUCTION: METAL/METAL OXIDE HALF CELL REACTIONS. Conference Paper uri icon

abstract

  • In an effort to understand the enhanced carbothermic reduction kinetics that are observed in the presence of a fused salt, an electrochemical system has been used to study a NiO/Ni half-cell in sodium carbonate at 1173 K. Steady-state potentiodynamic polarization and cyclic voltammetry measurements are reported as a function of oxide scale thickness and oxygen potential in the salt. The results for the electrochemical studies were correlated with electron micrographs to propose a mechanism for the reduction of NiO to nickel in the presence of a sodium carbonate fused salt. The applicability of an electrochemical mechanism to fused salt enhanced carbothermic reduction is also discussed.
