Synopsis: Galvanic cells to determine the interdiffusivity of two components in molten iron and slag were developed, using stabilized zirconia as an electrolyte, because it had been proved that local equilibrium held throughout the cell at high temperature. After getting a thermodynamic equilibrium in the cell, the oxygen potential and/or chemical potential of slag components at the electrode was changed rapidly by changing the gas phase or supplying a constant current to the cell.
