Methods for producing ceramic multi-layer components and multi-layer components made by such methods. A method includes the following steps: providing green layers for the ceramic multi-layer components, stacking the green layers into a stack and subsequently pressing the stack into a block, singulating the block into partial blocks each having a longitudinal direction, thermally treating the partial blocks and subsequently machining surfaces of the partial blocks. Recesses are produced on the surfaces of the partial blocks during the machining, and the partial blocks are singulated.

Method for producing ceramic multi-layer components

A method for producing a ceramic multilayer element is disclosed. In an embodiment the method includes forming a plurality of multilayer segments in a green state, wherein each multilayer segment is formed by pressing together a plurality of ceramic layers in the green state and pressing together the multilayer segments in the green state to form a multilayer element that is in the green state. The method further includes sintering the multilayer element that is in the green state to form a ceramic multilayer element that includes the ceramic layers and electrode layers arranged one on top of another, wherein at least one or more of a temperature at which the multilayer segments are pressed together, a pressing force applied during the pressing of the multilayer segments, and/or a duration of the pressing of the multilayer segments are adjusted.

Method for producing a multilayer element

A bracing element for bracing a piezoelectric multiple layer component includes a tubular body that is at least partially corrugated. A piezoelectric actuator with the bracing element is also disclosed.

Bracing element for bracing a piezoelectric actuator and piezoelectric actuator with the bracing element

A spring element for pretensioning a piezoelectric actuator is specified, wherein the spring element has a tubular body with recesses. The recesses are each made in the form of a polygon with rounded corners. A piezoelectric actuator with such a spring element is also specified.
