and Cu stabilizes the high temperature tetragonal γ′-phase at room temperature for composition x≥ 0.15. While the stabilization of orthorhombic β- phase is observed for composition x=0.10. It was found that the x = 0.17 composition has pronounced ionic conductivity of 05.28×10-3 S.cm-1at 300oC.The micrographs clearly distinguished between the grain and grain boundary area. AC impedance shows that the main conductivity is due to the grain contribution of the
