Phase formation and stability study of Sodium and Germanium incorporated Sr₃Si₃O₉ based system

The high ion conductivity and different alkali metal substitution strategy of the strontium silicate-based ion conductors have been enormously cross-examined by many researchers. Here, we discussed the investigation on the crystal structure, phase formation, microstructure, total conductivity and stability of the Sodium and Germanium incorporated Sr₃Si₃O₉ based system employing conductivity spectroscopic techniques. In this study, we also tried to get the optimal fabrication condition with compositions to minimize various issues of this system. And try to study the influence of various processing parameters on the phase formation. (author)
