Abstract: The present application relates to a method for producing ceramic multi-layer components (100), comprising the following steps: providing green layers (5) for the ceramic multi-layer components (100), stacking the green layers (5) into a stack and subsequently pressing the stack into a block (1), singulating the block (1) into partial blocks (3) each having a longitudinal direction (X), thermally treating the partial blocks (3) and subsequently machining surfaces of the partial blocks (3), wherein recesses (11) are produced on the surfaces of the partial blocks (3) during the machining, and singulating the partial blocks (3). The application further relates to a multi-layer component.

Abstract: 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.

Abstract: The present invention relates to a method for producing piezoelectric multi-layered components (2), which comprises the following steps: applying an electrode material (5) to green sheets (3) containing a piezoelectric material, applying a layer of a first auxiliary material (9) to at least one green sheet (3) containing the piezoelectric material, forming a stack (1), in which the green sheets (3), to which electrode material (5) is applied, are arranged one on top of another, wherein at least one ply of the green sheet (3), to which the layer of the first auxiliary material (9) is applied, is arranged in the stack (1), sintering the stack (1), wherein the layer of the first auxiliary material (9) is thinned, and firing the stack (1), wherein the stack (1) is singulated along the at least one ply into at least two multi-layered components (2).
