Abstract
Description
圧電セラミックは、いわゆる多層セラミック(積層素子または重層素子)として、なかでもセンサもしくはアクチュエータとして、圧電積層体(圧電スタック)の形で利用可能であり、かつ例えば燃料噴射系において使用される。センサもしくはアクチュエータとして使用される場合、圧電セラミックは、応力制御によって、より僅かな力の高い機械的変位を引き起こすか、または圧力制御によって高い電圧を生み出すのに用いられ得る。
請求項1に記載の本発明による低温で焼結するPZT混晶ベースの圧電材料(該圧電材料は、同様に請求項7に記載の本発明による方法によって製造され得る)は、先行技術と比べて、より低い温度で、多層アクチュエータとして適用するために、例えば自動車燃料噴射系において、従来公知のものより、なお良好な特性を得ることが出来るという利点を有する。
