Abstract
A beta-double prime aluminum oxide solid electrolyte (24) is prepared for wetting by a liquid electrode material. The method includes mechanically rubbing an asperity-filling metal against the surface (32) of the solid electrolyte (24) until the solid electrolyte (24) turns gray in color, which fills in asperities (34) in the surface (32) of the electrolyte (24). The electrolyte (24) and deposited asperity-filling metal (36) are heated to a temperature above the melting point of sodium, and sodium is de posited onto the electrolyte surface (32) and permitted to wick along the surface (32).
