Abstract: A blade for a cutting instrument, in particular for medical use, includes a first ceramic layer, a second ceramic layer, and a heating device arranged between the first ceramic layer and the second ceramic layer.

Abstract: A method for producing a receptacle for a sensor element, such as a combustion chamber pressure sensor, includes introducing a first amount of a pre-ceramic substance into an injection mold, forming a base layer of the receptacle by molding the pre-ceramic substance in the mold, and applying at least one conductor track to the base layer. A further amount of a pre-ceramic substance is introduced into the mold onto at least a partial region of the conductor track. A top region of the receptacle is formed directly on the base layer while at least partially covering over the conductor track by molding the further pre-ceramic substance in the injection mold. The method also includes debinding and sintering the molded body. The method forms a receptacle for a sensor element that has conductor tracks lying on the inside and incorporated in a gas-tight manner in a ceramic body.

Abstract: An electrochemical cell (10), in particular a fuel cell and/or an electrolytic cell and/or a metal-air cell, having at least one functional layer system (12), which is distinguished by the fact that at least one tubular support body (14) is formed, in which at least one tunnel-like structure (16) is formed, which adjoins the at least one functional layer system (12). A method for producing an electrochemical cell (10).

Abstract: A method for producing a tubular fuel cell by means of a pulling-core tool, the pulling-core tool comprising at least one tool part, which forms a cavity, and a pulling core, which can be positioned in at least two positions in the cavity.

Abstract: A ceramic composition for an injection-molding process for producing a combustion chamber pressure sensor, in particular for producing an insulation punch of a combustion chamber pressure sensor, includes a ceramic component in a proportion of greater than or equal to 50% by weight and a glass component in a proportion of less than or equal to 50% by weight. The ceramic component includes aluminum oxide. The glass component includes silicon dioxide or a silicon dioxide precursor. The ceramic composition further includes an alkaline earth metal oxide or an alkaline earth metal oxide precursor. The ceramic composition allows production of an insulation punch having a particularly good insulation capability. A ceramic injection-molding process includes the ceramic composition.

Abstract: The invention relates to a method for producing a tubular fuel cell by means of a pulling-core tool (11), wherein the pulling-core tool (11) comprises at least one tool part (12a, 12b) that forms a cavity and a pulling core (13) that can be positioned in at least two positions (A, B) in the cavity, wherein a hollow space (14, 14a) can be formed between the pulling core (13) and the at least one cavity-forming tool part (12a, 12b), which hollow space substantially corresponds to the shape of a tubular body to be formed, said tubular body being closed at one end by a cap section, wherein the pulling-core tool (11) has at least one sprue channel (15) that opens into the hollow-space region (14a) having the shape of the cap section.
