OSTI ID:91435
Na(I)-Beta-alumina is a high conductivity solid electrolyte for sodium ions with the general formula Na1+xMgxAl11-xO17, x+0.67. The high ionic but low electronic conductivity of Na(I)-Beta-alumina has made it a promising solid electrolyte for use in batteries and electrochemical devices, and thus a great deal of research has been devoted to the development of high-conductivity polycrystalline ceramics for these applications. It is also possible to exchange the Na(I) in Na(I)-Beta-alumina for a wide variety of mono-, di-, and trivalent cations. For example, complete or partial exchange occurs with at least 8 monovalent, 11 divalent, and 9 trivalent cations. This remarkable ion-exchange chemistry has produced many new and unusual compounds, most of which cannot be synthesized directly. Some have been shown to have possible applications as solid electrolytes and solid-state lasers.
