  • Glass compositions for gaskets of apparatuses operating at high temperatures and assembling method using them
    Patent number: 9309144
    Abstract: A glass composition, characterized in that it is selected from the group consisting of: a glass composition (A) with the following molar percentages: 70 to 76% of SiO2, 7 to 8% of B2O3, 5 to 6% of Al2O3, and 10 to 17% of Na2O; and a glass composition (B) with the following molar percentages: 63 to 76% of SiO2, 5 to 12% of ZrO2, 0 to 12% of B2O3, 0 to 2% of La2O3, 11 to 14% of Na2O, and 3 to 5% of K2O. The glass composition can be used in a method for assembling parts, in particular for a method of manufacturing high-temperature electrolyzers (HTEs) or high-temperature fuel cells (SOFCs).
