The diffusion of silver (Ag**1**1**0**m) was studied and the Haven ratio found for the first time at temperatures between 110 and 190 degree C. The diffusion coefficients were measured at 24 samples of the solid electrolytes at temperatures between 100 and 200 degree C while using the radiotracer in a thin layer and subsequently sectioning the samples. For 21 samples we obtained strictly linear relations between the distribution of activity and the square of distance, from which we calculated the diffusion coefficients at different temperatures. It is concluded that the errors in the measured values, which in the authors procedures were close to those found previously, that for Ag//6I//4WO//4 solid electrolyte the Haven correlation factor is practically unity.
