Abstract
When an electrical potential differenceE is applied by means of electron-conducting but otherwise inert electrodes to a solid compound with mixed ionic and electronic conductance, the compound is decomposed when the potential difference exceeds a critical valueE. This process is analysed theoretically and experimentally for the decomposition of Ag2S as a model sample. The critical electric potential differenceE * for the decomposition and the rate of decomposition are determined. Furthermore, the variation of the chemical potential of silver and the electrochemical potentials of silver ions and electrons within the sample are calculated and measured experimentally.
