Abstract: The disclosure relates to a bond produced with an at least partially crystallized glass, such as a metal-to-glass bond, in particular a metal-to-glass bond in a feed-through element or connecting element, and to a method for producing such a bond, in particular in a feed-through element or connecting element. The at least partially crystallized glass includes at least one crystal phase and pores which are distributed in the at least partially crystallized glass in a structured manner.

Abstract: A feed-through element of an ignition device for igniters of airbags or seatbelt tighteners is provided. The feed-through element has a metal support body, at least one first access opening in which a metal rod is arranged in an electrically insulating fixing material, and at least one second access opening in which a further metal rod is electrically conductively fixed to the support body by a soldered connection in this access opening. The support body and the access openings are configured as a shaped part. The feed-through element further includes a solder gap between the metal rod and the wall of the second access opening, where the solder gap has a small width.
