Abstract

Present work reports the Na-23, Si-29 NMR studies on the Sr0.55Na0.45SiO2.775 along with PXRD and ionic conductivity studies. NMR results indicate that Sr0.55Na0.45SiO2.775 consists of two phases, one being insulating alpha-SrSiO3 and other being a Na+ conducting amorphous Na2Si2O5. High temperature heat treatment of Sr0.55Na0.45SiO2.775 leads to the crystallization of amorphous phase into different polymorphs of Na2Si2O5 phase.
