Method for Producing a Piezoelectric Multilayer Component and a Piezoelectric Multilayer Component

摘要

A method for producing a piezoelectric multilayer component is disclosed. Piezoelectric green films and electrode material are provided, arranged alternately on top of one another and sintered. The electrode material is provided with a PbO-containing coating and/or PbO is mixed into the electrode material.

主权项

1. A piezoelectric multilayer component comprising:
a stack of sintered piezoelectric layers and inner electrodes arranged between the piezoelectric layers, wherein a region that comprises poling cracks is present on a surface of at least one of the inner electrodes; and wherein the region that comprises poling cracks has at least one of a PbO content that is greater than a PbO content of the piezoelectric layers, and traces of PbPdO2.
