Abstract
Na5YSi4O12-type Na+-superionic conductor Narpsio in the Na2O-Y2O3-P2O5-SiO2 system was prepared,and Na+-ion exchange with other cation (Li+) in the Narpsio was performed. Field-assisted Na+-ion exchange by Li+ in Narpsio was performed from solutions containing Li+ ions. Before and after in exchange ceramics were characterized by XRD, and also their electrical properties were measured.
