Zusammenfassung:	Novel glass compositions and method for producing a glass/metal join, in which the novel glass comprises: Oxide (%) B2O3 8-13.5 Al2O3 5-9 Na2O 3-9 K2O 0-5 CaO 2-4 MgO 0-4 ZnO 0-4 SiO2 Up to 100 depending on the necessary requirements, owing to the significance thereof the thermal expansion coefficient, such that this thermal expansion coefficient is adjusted to match that of the metal part or alloy with which the glass/metal weld is to be achieved, which makes it possible to satisfactorily produce said weld which results in a strong glass/metal join, that is free from tensile stresses and that is durable over time and may be used, inter alia, to obtain parts that form part of solar collectors.
