Patent number: 9598319Abstract: According to the state of the art, piezoceramic multi-layer elements are sintered in air at temperatures of approximately 1100 DEG C or higher. Therefore, only a noble metal having a high melting temperature can be used as the inner electrode. Non-noble metals would oxidize. Therefore, a silver-palladium alloy having up to 40% palladium is normally used. However, such a measure is associated with high material costs. Lower melting temperatures of the inner electrode material, however, also require a ceramic material having correspondingly low sintering temperatures. The invention therefore proposes that an electrically non-conductive sintering additive added be added to the base material, and that the inner electrode comprise silver, preferably pure silver, as the main material component thereof, and an electrically non-conductive material component and/or a metal alloy or metal oxide mixture.Type: GrantFiled: October 20, 2008Date of Patent: March 21, 2017Assignee: CeramTec GmbHInventors: Reiner Bindig, Hans-Jurgen Schreiner
