Abstract:

The kinetics of interfacial chemical reaction noise at sodium amalgam and NaI propylene carbonate contacts to NaBetaAlumina are examined by determining the time and temperature dependence of the noise. The rate constant for the reaction noise is larger for amalgam contacts and increases with sodium concentration in both cases. The noise is thermally activated with an activation energy of 0.5eV, which is similar to that of bulk diffusion noise in NaBetaAlumina. Keywords Diffusion noise, Conductivity fluctuations, Superionic conductors, Beta alumina ceramics, Single crystals.
