Electrical properties of a new Ag+ ion conducting glassy system:: x[0.75AgI:0.25AgCl] : (I-x)[Ag2O : P2O5]

A new fast Ag+ ion conducting glassy system: x[0.75AgI:0.25AgCl]: (1-x)[Ag2O: P2O5] where 0.1 less than or equal to x less than or equal to 1 in molar weight fraction, has been synthesized by melt-quench technique using a high-speed twin roller-quencher. An alternate host salt: 'quenched [0.75AgI: 0.25AgCl] mixed system/solid solution', has been used in place of the traditional host AgI. The compositional dependence conductivity studies on the glassy systems: x[0.75AgI:0.25AgCl]: (1-x)[Ag2O: P2O5] as well as xAgI: (1-x)[Ag2O: P2O5] prepared identically, indicated that the composition at x = 0.75 exhibited the highest room temperature conductivity. The composition: 0.75[0.75AgI: 0.25AgCl]: 0.25[Ag2O: P2O5] has been referred to as optimum conducting composition (OCC). The study also revealed that the new/alternate host yielded better electrolyte system. The activation energy (Ea), involved in the thermally activated conductivity process has been computed from 'log sigma - 1/T'Arrhenius plot.
