Abstract
(DE)
Die vorliegende Erfindung betrifft kristallisierende Glaslote und Komposite, die insbesondere für Hochtemperaturanwendungen geeignet sind, und deren Anwendungen z.B. in Brennstoffzellen. Das kristallisierende Glaslot beinhaltet in Gew.-% 25 % bis 40 % SiO2, 45 % bis 60 % BaO, 5 % bis 15 % B2O3, 0 bis <2 % AI2O3 sowie zumindest ein Erdalkalioxid aus der Gruppe MgO, CaO und SrO wobei CaO 0 % bis 5 % beträgt und zeichnet sich durch einen thermischen Ausdehnungskoeffizienten im Temperaturbereich von 20 °C bis 300 °C von 8,0⋅10-6 K-1 bis 13,0⋅10-6 K-1 aus.
(EN)
The present invention relates to crystallizing glass solders and composites, which are suited in particular for high-temperature applications, and to applications thereof, such as in fuel cells. The crystallizing glass solder contains 25% to 40% by weight of SiO2, 45% to 60% of BaO, 5% to 15% of B2O3, 0 to <2% of AI2O3 and at least one alkaline earth oxide, selected from the group consisting of MgO, CaO and SrO, wherein CaO is 0% to 5% and is characterized by a thermal expansion coefficient of 8.0⋅10-6 K-1 to 13.0⋅10-6 K-1 in the temperature range of 20°C to 300°C.

La présente invention concerne des verres de soudure et composites cristallisants qui conviennent notamment pour des applications à température élevée, et leurs utilisations par exemple dans des piles combustible. Le verre de soudure cristallisant contient en % en poids de 25 % à 40 % de SiO2, de 45 % à 60 % de BaO, de 5 % à 15 % de B2O3, de 0 à <2 % de AI2O3 ainsi qu'au moins un oxyde de métal alcalino-terreux du groupe composé de MgO, CaO et SrO, CaO représentant de 0 % à 5 %. Le verre de soudure cristallisant se caractérise par un coefficient de dilatation thermique dans la plage de température de 20° C à 300° C de 8,0⋅10-6 K-1 à 13,0⋅10-6 K-1.
