Abstract

Na+ ion-conducting solid electrolyte of sodium nitrate (NaNO3) and Sr(NO3)2 mixed crystals were grown by slow evaporation technique. XRD, FTIR, SEM characterizations and AC, DC conductivities were carried out on the pellets. Conductivity in these mixed solid electrolytes was noticed to increase with increase in m/o Sr(NO3)2 upto 14.68 followed by decrease. The conductivity in 14.68 m/o Sr(NO3)2 is more than one order of magnitude as compared to NaNO3 in the extrinsic region. Ionic transport in these mixed systems is explained.
