Beta alumina solid electrolyte and method of preparing the same

摘要

A beta alumina solid electrolyte (BASE) and a method of preparing the same are provided. When the method is used, evaporation of sodium is suppressed and thus a beta alumina solid electrolyte having a high density, a low porosity, and a composition that is near a desired (target) composition is produced.
