CRYSTALLIZING GLASS SOLDER AND USE THEREOF

摘要

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 2O3 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.
