Title
(DE) Kristallisierendes Glaslot, Komposite und dessen Verwendung
(EN) Crystallizing glass solder, useful e.g. to produce high temperature joints for fuel cells, comprises barium oxide, silicon dioxide, boric oxide, aluminum oxide and alkaline earth oxides comprising oxides of magnesium, calcium or strontium
Abstract
(DE)

Kristallisierendes Glaslot für Hochtemperaturanwendungen, enthaltend (in Gew.-% auf Oxidbasis) 45% bis 60% BaO, 25% bis 40% SiO2, 5% bis 15% B2O3, 0 bis < 2% Al2O3, 0 bis < 7% CaO, sowie zumindest ein Erdalkalioxid aus der Gruppe MgO, CaO und SrO, wobei die Summe der Erdalkalioxide MgO, CaO und SrO bis 20%, bevorzugt 2% bis 15% beträgt.

(EN)

Crystallizing glass solder comprises barium oxide (BaO) (45-60 wt.%), silicon dioxide (SiO 2) (25-40 wt.%), diboron trioxide (B 2O 3) (5-15 wt.%), aluminum oxide (0 to less than 2 wt.%), and at least one alkaline earth oxide comprising magnesium oxide (MgO), calcium oxide (CaO) or strontium oxide (SrO), where the sum of MgO, CaO and SrO is up to 20 (preferably 2-15) wt.%. An independent claim is included for a composite comprising the crystallizing glass solder and up to 35% of crystalline filler.
