ABSTRACT:
Sodium resistant sealing glasses have aluminoborate glass compositions in which glass stability is improved by the incorporation of specific mixtures of modifying alkali earth oxides of calcium oxide, strontium oxide and barium oxide. These modifying alkali earth oxides are present in a total weight percent range from 15 to 40 weight percent of the glass composition.
Also disclosed is the employment of the above glasses as seals in sodium-sulfur cells.
