Abstract
Ceramic materials are disclosed which have comprehensive characteristics of high ion-conductivity for alkali metal cations at low temperatures, high selectivity for alkali metal ions, good current efficiency and stability in water and corrosive media under static and electrochemical conditions. Also disclosed is an electrochemical cell, the electrolyte of which employs the disclosed ceramic materials, for use in electrolysis of aqueous alkali salt solutions to form caustic.
