Abstract: A method for producing an electronic component includes providing a piezoelectric main body, which is provided with electrodes. A first electric polarization field having a first polarity direction is applied to the piezoelectric main body between the two electrodes and then a second electric polarization field is applied in a second polarity direction, opposite to the first polarity direction, to the piezoelectric main body between the electrodes. The absolute value of the second electric polarization field differs from that of the first electric polarization field.

Abstract: A method can be used for producing ceramic multilayer components. The method includes providing green layers for the ceramic multilayer components, stacking the green layers into a stack, and subsequently compressing the stack to form a block. Furthermore, the method includes isolating the block into partial blocks that each have a longitudinal direction, thermally treating the partial blocks, subsequently mechanically machining surfaces of the partial blocks, and providing the partial blocks with outer electrodes and isolating the partial blocks in each case transversely to the longitudinal direction into individual ceramic multilayer components.
