Ionic transport in the (Agl∶AgCl) mixed-system
- 50 Downloads
Ionic mobility, conductivity, number of charge carriers and transference number are reported for annealed and rapidly quenched [xAgl∶(1−x)AgCl] mixed systems, these results are compared with Agl. Of these three materials the quenched mixed-system had the highest Ag+ ion conductivity. Further, preliminary studies are reported where the high conductivity system (i.e. quenched 0.75 Agl∶0.25 AgCl) has been used as host material for the preparation of Ag+ ion conducting glasses and composites. Detailed thermal/phase diagram studies have also been carried out on the quenched composition. The conductivity enhancement in the quenched system is attributed to the formation of new disordered phases and the introduction of amorphisity, the simple space-charge model applicable to the annealed system failed to explain these results.
