Abstract: One aspect relates to an electrical bushing for an implantable device including an electrically insulating base body and at least one electrically conductive bushing body that is embedded in at least one bushing opening that extends through the base body. The base body is produced from a sintered ceramic material, characterized in that the at least one bushing body is made of a sintered cermet material or a sintered metallic material. The base body and the at least one bushing body comprise a firmly bonded sintered connection.

Abstract: One aspect relates to a method for producing an electrical bushing for an implantable device, an electrical bushing, and an implantable device. The method according to one embodiment includes forming a base body from a ceramic slurry and introducing a bushing conductor made of a metal powder, metal slurry, cermet powder and/or cermet slurry into the base body. The metal fraction in the bushing conductor is provided to decrease towards the base body. It includes sintering the green blank that includes the base body and the bushing conductor.

Abstract: Methods for reducing the evaporation rate of platinum and Pt alloys upon their use at high temperatures >1,200° C. in an oxidizing atmosphere include the steps: (A) providing a component made of platinum or a platinum alloy; (B) wrapping the outer surface of the component with a flexible bandage having open porosity and provided with an oxide ceramic material and/or a glass-forming material; (C) using the component at operating temperatures >1,200° C. Methods for scavenging noble metal oxides evaporating or sublimating from the surface of platinum or Pt alloys include: (A) providing a component made of platinum or a platinum alloy; (B) wrapping the outer surface of the component with a flexible bandage having open porosity; and (C) using the component at operating temperatures >1,200° C. Correspondingly wrapped components are also provided.

Abstract: One aspect relates to a method for producing an electrical bushing for an implantable device, a corresponding electrical bushing, and a corresponding implantable device. The method according to one embodiment is characterized in that a green blank is produced and sintered from an electrically insulating base body green blank made of a ceramic slurry or powder and at least one electrically conductive bushing body green blank made of a cermet material. The at least one bushing body green blank is inserted into a bushing opening of the base body green blank to form a composite green blank, a shape of the at least one 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 bushing body green blank through the bushing opening. The composite green blank is sintered while applying a force that keeps the bodies together.

Abstract: Castings made of boron-containing alloys based on at least one platinum group metal are treated by thermal ageing in the presence of oxygen and at temperatures below the melting point of the alloy. This enables the alloys to be processed at temperatures customary in the jewelry industry. The treated castings can also be processed into medical technology products.
