Abstract: The invention relates to a method for producing a component from ceramic materials in which a plurality of layers are applied to a base body by means of screen printing or template printing, said layers being formed from a ceramic material, in each case in a defined geometry above one another in the form of a paste or suspension in which powdery ceramic material and at least one binder are included. At least one region is formed here within at least one layer having a defined thickness and geometry composed of a further material that can be removed in a thermal treatment and that is likewise applied in the form of a paste or suspension by means of screen printing or template printing. Electrically functional structures composed of an electrically conductive or semiconductive material are applied to and/or formed on and/or in at least of the ceramic layers prior to the application of a further ceramic layer.

Abstract: The invention relates to a process for producing an electrochemical cell, particularly a solid-electrolyte battery, wherein a paste or foil is applied to each of the opposing surfaces of a solid electrolyte that form the respective anode and the respective electrode, and organic components within the pastes or foils are expelled in a heat treatment under an inert or reducing atmosphere. Subsequent to this, in a further stage, a fusional connection is produced by sintering between the anode and the solid electrolyte and between the cathode and the solid electrolyte. Here, the solid electrolyte is formed with an oxidic material conductive for lithium ions, the anode with a first lithium-containing chemical compound, particularly lithium titanate, and carbon, and the cathode with a second lithium-containing chemical compound, particularly a lithium metal phosphate, and carbon, to give a three-layer electrochemical cell construction devoid of organic components.

Abstract: The invention relates to the field of multilayer ceramics and relates to ceramic pressure sensors, such as can be used, for example, for industrial process control. The object of the invention is to disclose ceramic pressure sensors that are mounted in a largely mechanically stress-free manner and have a long service life, and the production of which is more effective and more cost-effective. The object is attained with ceramic pressure sensors, comprising a support of tapes, wherein the tape(s) embody at least one cavity that is covered with at least one ceramic pressure membrane tape or in which a ceramic pressure membrane tape covering the cavity is located, and wherein the tape(s) have at least one supply line for the pressure connection to the cavity, and the tape composite is sintered.

Abstract: A compound body comprises a steel base element on which is deposited a heater layer. The base element is made of a precipitation hardening steel. In the form of a manifold or material feed tube in a hot duct system, said base element comprises a round or convex surface receiving the heater layer. This heater layer is a compound layer having several strata and/or strata elements which are thick film pastes or sheets and in such form are consecutively deposited, dried and baked-on. The pre-compression generated in this process in the heater layer is increased in controlled manner by precipitation hardening the base element.
