摘要：

Na+ ions in the solid electrolyte beta- and beta''-alumina can be replaced by monovalent, divalent and trivalent ions. Ion exchange experiments have been carried out with polycrystalline samples, as well as with single crystals of the superionic conductors, and with solid or molten lanthanide trichlorides. The extent of exchange was controlled by the temperature and time, achieving exchange rates of up to 100%. The lanthanide-ion-exchanged beta- and beta(n)-alumina were characterized by X-ray methods. Some tailored spectroscopic and electrical properties are presented.
