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. The layer structure is then sintered in a thermal heat treatment, with the further material being removed and at least one hollow space being formed with defined dimensions of width, length, and height.

Method for producing a component from ceramic materials

In the electrical energy storage element in accordance with the invention, a plurality of electrochemical cells that are each formed with a cathode and an anode as electrodes and an electrolyte are arranged stacked above one another. They are enclosed at one side by a top plate formed from an electrically conductive material, in particular aluminum, and at the oppositely disposed side by a base plate formed from an electrically conductive material, in particular aluminum. The base plate is coated by a cathode or by an anode and the cover plate is coated in a complementary manner by an anode or by a cathode. The anodes and cathodes are each formed at oppositely disposed surfaces of an electrically conductive carrier film which preferably comprises aluminum, copper, steel or an electrically conductive plastic. An outer peripheral margin is present at the carrier film that is free of electrode material and connects adjacent electrochemical cells to one another in a hermetically sealed manner with respect to the environment by means of a sealing and bonding agent. The anodes comprise a lithium titanate (LTO) having a spinel structure and the high-voltage cathodes are formed from a lithium nickel manganate (LNMO) having a spinel structure or from lithium phosphates (LP) in an olivine structure. With a gel electrolyte, a respective separator layer is present between the electrolyte and an electrode of an electrochemical cell and with a solid electrolyte no separator layer is present.

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. The object is further attained with a method for production, in which at least one tape is structured for producing a cavity, at least one pressure membrane tape is positioned on the cavity for covering, and subsequently the tape composite is sintered.

Ceramic pressure sensors and method for producing the same

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.
