Abstract:

Ion exchange reactions were used to substitute divalent and trivalent cations for the entire sodium ion content of sodium beta alumina. A wide range of divalent and trivalent beta aluminas were synthesized which exhibited conductivities much greater than any other divalent or trivalent solid electrolyte in the 300-400 deg C range. The multivalent beta aluminas greatly extend the opportunities for electrochemical sensors based on solid electrolytes. Author
