| Abstract: | The effect of annealing upon the isothermally measured complex impedance of some Ag/M2XO4 symmetrical cell systems (with M=Na, Ag and X=S, W) is studied. One can distinguish between four effects: (1) The growth of intergrain contact in the electrolyte pressed pellet. (2) Plastic deformation of the electrolyte pellet. (3) Mechanical formation of the interface. (4) Chemical corrosion at the Ag/Na2XO4 interface in air. The correlation between these phenomena is discussed. |
