Steady-State Chemical Potential Profiles in Solid Electrolytes

Steady‐state chemical potential profiles in a solid electrolyte under open‐ circuit and ion‐blocking conditions, may be obtained by balancing the steady‐ state flux at points inside the electrolyte. Steady‐state oxygen chemical potential profiles inside a scaling layer of thoria and inside yttria‐doped thoria specimens under open‐circuit and ion‐blocking (d‐c polarization) conditions are illustrated in special cases.
