  • Sodium resistant sealing glasses and sodium-sulfur cells sealed with said glasses
    Patent number: 4341849
    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.
    Type: Grant

  • Sodium resistant sealing glasses
    Patent number: 4268313
    Abstract: Sodium resistant sealing glasses having borosilicate glass compositions in which glass stability is improved by the incorporation of several percent sodium oxide with a select percentage of the alkali earth oxides of calcium oxide, strontium oxide and barium oxide. The sodium oxide is present in the sealing glass compositions in a total weight percent range from 2 to 6 weight percent. Each of the alkali earth oxides is present in the glass compositions in the range from 2 to 8 weight percent with the total of the three oxides not exceeding 16 weight percent.
