Piezoelectric component used as an actuator in a piezo-stack consists of a stack of ceramic layers with a copper electrode layer between the ceramic layers

摘要

Piezoelectric component consists of a stack of at least two ceramic layers with a copper electrode layer between the ceramic layers. An independent claim is also included for a process for the production of a piezoelectric component comprising forming a stack of ceramic green foils containing a binder and electrode layers and then removing the binder in an atmosphere containing an inert gas and oxygen, the oxygen content being reduced by adding a suitable amount of hydrogen gas or by gettering so that the electrode layers are not damaged.
