Contact Noise in Sodium Beta 11 Alumina.
Abstract
Contact noise in sodium beta alumina cells has been measured at frequencies from .0001 to 30000 Hz. The propylene carbonate solution appeared good wetting with the beta alumina and had a low noise level. The noise spectra for aqueous solution, silver amalgam and newly prepared mercury electrodes, however, showed a slope of -2 at low frequencies, that suggests non-equilibrium reactions occurred at the interface. After current flow, the contact noise of aqueous electrode decreased, but that of mercury electrode increased temporarily and showed f to the -1.5 power dependence, suggesting diffusion process.
