Abstract:

The qualitative comparison of the impedance behavior of the three calls platinumsilver conducting glass Ag beta alumina Ptglass Pt and Pt beta Pt leads to the conclusion that the properties of the cell Pt glass beta Pt are determined by those of the interfaces Pt glass and beta Pt at low and intermediate frequencies. At high frequencies the contributions of the bulk impedances become predominant. A contribution from the impedance of the interface glass beta is small with respect to the other contributions. The transfer of the Ag ion from the amorphous glass phase into the crystalline beta alumina is rapid.
