摘要:
A ceramic element includes at least one substantially homogeneous ceramic layer which is provided with a plurality of superimposed partial ceramic layers. The ceramic element can be produced by stacking partial homogeneous ceramic layers on top of each other in the form of ceramic green films, removing the binding agent, and sintering. The ceramic element can be compacted at a lower sintering temperature than conventional block sinters. Moreover, the ceramic layer of the ceramic element is provided with a low number of pores, enclosures, foreign phases, and other flaws and is highly homogeneous. The ceramic element particularly represents a piezoelectric bending transducer or a piezoelectric transformer. Advantageously, the bending transducer or transformer has electrodes so as to be electrically triggered, the electrodes being buried underneath another ceramic layer. The additional ceramic layer and/or the electrode layer are used as a diffusion barrier.
