Abstract:
1. A method for producing an electrical bushing for an implantable device, whereby a composite green blank is produced and sintered from an electrically insulating base body green blank and at least one electrically conductive bushing body green blank, the method comprising: forming the base body green blank from a ceramic slurry or a ceramic powder such as to have at least one bushing opening that extends through the base body green blank; forming the at least one electrically conductive bushing body green blank from a cermet slurry, a cermet powder, a metal powder and/or a slurry made of a metal powder, whereby a shape of the at least one electrically conductive bushing body green blank and a shape of the at least one bushing opening are complementary to each other at least in sections thereof and prevent slippage of the electrically conductive bushing body green blank through the at least one bushing opening; inserting the at least one electrically conductive bushing body green blank into the at least one bushing opening of the base body green blank to form the composite green blank; and applying at least one force to the electrically conductive bushing body green blank and/or the base body green blank and sintering the composite green blank while applying the at least one force, whereby the at least one force is directed in a direction of a bracketing of the at least one bushing body green blank in the at least one bushing opening of the base body green blank.
