Abstract:
Vitreous or at least partly crystallized sealing material is provided. The sealing material is from the system SiO2—B2O3—CaO—MgO, which is free from BaO and/or SrO and which has an improved coefficient of thermal expansion and improved crystallization properties. The sealing material is employed to produce joint connections, electrical feedthroughs, and/or as a barrier layer.
