CHARACTERISTIC OF (AgI)0.44(LiI)0.22(AgPO3)0.34 IONIC CONDUCTOR PREPARED BY MELT QUENCHING METHOD

Characterization of (AgI)0.44(LiI)0.22(AgPO3)0.34 ionic conductor prepared by melt quenching method have been carried out by using X-Ray Diffractometer (XRD), Differential Scanning Calorimeter (DSC) and Inductance (L) Capacitance (C) Resistance (R) meter. X-ray diffraction pattern shows that the compound has a mixture of amorphous and small amount of crystalline form with several Bragg peaks correspond toAgI. The DSC thermograph shows that an endothermic peak at temperature ~420 K matches with the phase transition ofAgI which reinforces that a number ofAgI are not dissolved in the material of (AgI)0.44(LiI)0.22(AgPO3)0.34. The obtained dc ionic conductivity is around ~10-2 S/cmat ambient temperature. The activation energy has two values, 0.20 eV below ~380 K and 0.15 eV above ~380 K.
