Various compositions of silver conducting glasses [AgI – Ag2O-P2O5-Fe2O3 ] were prepared by melt quenching technique. X-ray diffraction (XRD),Mossbauer effect (ME), infrared (IR), differential thermal analysis (DTA) studies were carried. Dielectric measurements have been carried out on (50-x)P2O5-xAgI-40Ag2O-10Fe2O3 ,[x=0,5,10,15,20,30] glasses from 50 Hz upto 5MHz.The frequency dependence of the total conductivity is nearly constant at the low frequency, identified with the true dc ionic conductivity sdc (0) and at high frequencies an additional term increasing in a power law with exponent s<1 corresponds to translational hopping motion.Effect of frequency and temperature on dielectric constants and dielectric loss is studied. The general behaviour of e?? shows a decrease with increasing frequency following a power relation with exponent m>1 and activation energy values of Wm about 0.042-0.016 eV lower than obtained using dc conductivity.
