Abstract

Upon passing small currents (1 to 25 mu amp) through the cell: Cu, Cu//2O vertical Cu vertical ZrO//2 (7. 5 wt % caO) vertical Cu vertical Cu, Cu//2O steady-state overvoltages have been determined at temperatures between 800 and 1000 degree C. Quantitative analysis of the results confirms that the steady-state overvoltage is established by oxygen concentration gradients in the copper-foil electrodes. The solubility-diffusivity product of oxygen in solid copper has been calculated from the measured overvoltages. Values for the diffusivity of oxygen in copper have also been obtained.
