Abstract:

The mixture of (AgI)0.33(LiI)0.33(LiPO3)0.34 was synthesized by melt quenching method. The material then was characterized by XRD, DSC, and LCR-meter. The X-ray diffraction pattern shows an amorphous structure with some Bragg peaks correspond to the crystalline of AgI, and the thermal behavior shows an endothermic peak at temperature ~ 420 K which matches with the phase transition of the β to α-AgI. They show that a number of AgI were not dissolved in the material of (AgI)0.33(LiI)0.33(LiPO3)0.34. The ionic conductivity of this new material at room temperature is around 1.7 x 10-2 S/cm. This is much larger compared with the conductivities of the constituent compounds of AgI, LiI and LiPO3 as well as the LiI-LiPO3 and AgI-LiPO3 systems. The activation energy of this material is 0.15 eV, which is similar to AgI (0.14 eV). This result suggested that the high concentrations conduction is mainly due to silver ions.
