A feed-through component for a conductor feed-through which passes through a part of a housing, for example a battery housing, is embedded in a glass or glass ceramic material and has at least one conductor, for example an essentially pin-shaped conductor, and a head part. The surface, in particular the cross-sectional surface, of the head part is greater than the surface, in particular the cross-sectional surface, of the conductor, for example of the essentially pin-shaped conductor. The head part is embodied such that is can be joined to an electrode-connecting component, for example an electrode-connecting part, which may be made of copper, a copper alloy CuSiC, an aluminum alloy AlSiC or aluminum, with a mechanically stable and non-detachable connection.

A molding composite includes mica flakes and a eutectic glaze. The composite allows making of lead-free parts for use in a variety of situations, such as electrical insulators for supporting electrically-conductive parts, such as electrodes, for electrical devices. The molded composite material can be used mold around such electrically-conductive parts, supporting them and/or providing hermetic seals around the parts. Other possible uses include substrates for electronic circuits, and housings for parts, such as electro-optical parts. The molding composite is heated under elevated pressure to liquefy the eutectic glaze, causing it to coat the mica flakes. After the composite is put into a desired shape it is solidify, for example by compressing the molding composite at a constant temperature until the eutectic glaze solidifies, followed by cooling of the molding composite.
