摘要
The phenomenon of ionic transport in the case of two different mixed systems (CuI)(1−x)–(Ag2WO4)x(0.15≤x≤0.6) and (CuI)(1−y)–(Ag2CrO4)y(0.15≤y≤0.5) has been investigated. Powder X-ray diffraction (XRD) analysis coupled with differential scanning calorimetry (DSC), Fourier transform infrared (FT-IR), FT-Raman and electrical transport studies involving ionic transport number and temperature-dependent electrical conductivity measurements have been carried out in order to identify the various phases responsible for the conduction process. The occurrence of typical ionic conductivity values of 4.5×10−3Scm−1 for the composition (CuI)0.45–(Ag2WO4)0.55 and 1.1×10−4Scm−1 in the case of (CuI)0.55–(Ag2CrO4)0.45 at room temperature has been discussed in terms of the observed characteristics.
