  • Glass composition formulated for a glass-metal bond of a tube collector and glass-metal bond made with glass of said glass composition
    Patent number: 8178451
    Abstract: The glass-metal bond for a tube collector includes a glass tube and metal part bonded to the glass tube. In order to match the thermal expansion properties, the glass tube has the following composition: SiO2, 73-77 wt. %; B2O3, 6-<8 wt. %; Al2O3, 6-6.5 wt. %; Na2O, 5.5-7 wt. %; K2O, 1-3 wt. %; CaO, 0.5-3.2 wt. %; MgO, 0-2 wt. %; Fe2O3, 50-150 ppm; and TiO2 0-<100 ppm. The ratio of the sum of the alkaline-earth metal oxides (in mol %) to the sum of the alkali metal oxides (in mol %) is ?0.6. The metal part is preferably made of metal material no. 1.3981 according to DIN 17745. The glass composition itself is also part of the invention.
