COMPOSITION FOR FORMING CERAMIC ELECTROLYTE, AND RESULTING ELECTROLYTE
A composition is provided for forming a sodium-ion conducting electrolyte structure, comprising particles of a sodium-ion-conducting ceramic, combined with particles of at least one transition metal oxide, such as copper, titanium and niobium oxides, or iron oxide, or precursors for these oxides, so the metal oxides make up no more than 5% by weight of the weight of the particles. The sodium-ion-conducting ceramic may be of the types referred to as Nasicon, or ß''-alumina. The metal oxides may constitute no more than 2% of the weight of the particles. The metal oxides act as a sintering aid, making it possible to achieve densification at a reduced sintering temperature, while having no significant detrimental effect on the electrical properties of the sintered ceramic. The invention also encompasses an electrode structure made by sintering this composition.
