Abstract
The amorphous, or at least partially crystalline, glass-based joining material is suitable for high-temperature applications, particularly in fuel cells and/or sensors. In addition to SiOand BOas glass formers, the joining material similarly contains BaO and CaO, whereby the amount of AlOis limited. The joining material has a coefficient of linear thermal expansion of at least 7.0·10Kin a range of 20° C. to 300° C. The joining material can be used for joining ferritic high-grade steels and/or chromium-containing alloys and/or ceramics, such as stabilized zirconium oxide and/or aluminium oxide.
