H. Nafe et M. Steinbruck, ELECTRONIC CONDUCTIVITY OF POLYCRYSTALLINE NA-BETA-ALUMINA AT HIGH-TEMPERATURE, Journal of the Electrochemical Society, 141(10), 1994, pp. 2779-2783
From defect chemical considerations the sodium potential dependencies
of the partial electronic conductivities of Na-beta-alumina are derive
d. As a result, relationships for the ionic transference number, the o
pen-circuit voltage of a galvanic cell, the steady-state ionic current
and the sodium potential profile across the electrolyte can be solved
for. These relationships serve as a theoretical basis to determine an
d discuss the role of the partial electronic conductivities under defi
ned operating conditions of the electrolyte.
