Ion conduction is considered through electrolytes containing an immobile gradient in the electronic/ionic transport number ratio. It is shown that internal deposition of the metal phase (reduced ions) can occur in such electrolytes during electrolysis. A ''critical'' applied voltage or current density can be formulated above which electrolyte fracture would be caused by the internally deposited material. Application of the analysis to the sodium-beta alumina type electrolytes leads to identification of factors that could contribute to electrolyte degradation. 16 refs.
