Abstract: 
The anodic dissolution of silver at the solid-solid interface Agl alpha-AgI has been studied by means of a high precision (capacitive) dilatometer. The dilatometer signal corresponds to the change of the anode thickness during the dissolution experiment. Under galvanostatic conditions and in a definite pressure range the dilatometer signal oscillates periodically, i.e., the length change of the anode with time is not a simple and linear function of the current density. The mean length change is, as expected, proportional to the electric current. The oscillation modes of the dilatometer signal are correlated with simultaneous electrochemical oscillations at the anode and give evidence for the influence of morphological effects on the interface kinetics. From the combination of both electrochemical and dilatometric (mechanical) experiments, we draw conclusions on a possible mechanism of the observed oscillatory kinetics.
