dc.description.abstract In this work, for the first time, we systematically evaluated the temperature-dependent long-term stability of Na-doped SrSiO3 super ionic conductors. The total conductivity of the Sr0.6Na0.4SiO2.8 (40SNS) was monitored in situ by electrochemical impedance spectroscopy. The conductivity of the 40SNS at 700 °C degraded within 1 h due to the crystallization of Na2Si2O5. However, at 450 °C, the initial conductivity of the 40SNS was firmly maintained for 260 h without any observable phase transition. These results demonstrate the existence of a threshold temperature regime that suppresses the crystallization kinetics of the amorphous phase of Na-doped SrSiO3 materials. © 2018 The Korean Society of Industrial and Engineering Chemistry -
