Frequency response analysis of ionically conducting mixed system (1-x)CuI - xAg2MoO4 (0.15 ≤ x ≤ 0.55)

Article

Abstract

A systematic analysis of the electrical response of the mixed system (1-x)CuI — xAg2MoO4 (0.15≤x≤0.55) over the temperature range 297 – 447 K in the 20 Hz — 1 MHz frequency domain has been reported. Relaxation processes associated with individual compositions of this heterogeneous mixture of polycrystalline samples have been identified through a combined analysis of modulus and impedance spectral formalisms. The detailed analysis of these relaxation processes has indicated that AgI and Ag2MoO4 phases are the predominant sources of electric conduction in the case of samples in the composition region 0.33≤x≤0.55 whereas in those samples having x<0.33, the presence of Cu2MoO4 phase in the mixture is found to make a definite contribution to their effective electric conduction.
