Characteristic of (Agi)0.44 (Lii)0.22 (Agpo3)0.34 Ionic Conductor Prepared by Melt Quenching Method

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-RayDiffractometer (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 formwith 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

Derivation of Inter-Atomic Force Constants of Cu2O from Diffuse Neutron Scattering Measurement

Neutron scattering intensity from Cu2O compound has been measured at 10 K and 295 K with High Resolution Powder Diffractometer at JRR-3 JAEA. The oscillatory diffuse scattering related to correlations among thermal displacements of atoms was observed at 295 K. The correlation parameters were determined from the observed diffuse scattering intensity at 10 and 295 K. The force constants between the neighboring atoms in Cu2O were estimated from the correlation parameters and compared to those of Ag2O.Received: 16 January 2013; Revised: 10 April 2013; Accepted: 15 April 201
