ABSTRACT OF THE DISCLOSURE This invention is directed to the production of sealing glasses capable of forming strong, non-porous seals with glasses containing at least 10% by weight of an alkali metal oxide such as are used in the fabrication of the glass membranes utilized in sodium-sulfur and potassium-sulfur batteries. The inventive seals require an interdiffusion of ions to occur between the sealing glass and the glass being sealed. Glasses presently employed as membrane glasses for such batteries have base compositions within the Na2O-B2O3 and X2O-B2O3 systems. The inventive sealing glasses consist essentially, expressed in mole percent on the oxide basis, of about 3-30% R2O and 60-95% B2O3, wherein R2O consists of K2O, Rb2O, Cs2O, and mixtures thereof and, optionally, Al2O3 is substituted for up to one-half the E2O3 content on a molar basis. The seals contemplate the exchange of large alkali metal ions from the sealing glass for the smaller alkali metal ions of the membrane glass.
