Abstract

Keramische Werkstoffe sind spröde und deshalb in der Regel nicht für dynamische Belastungen, insbesondere durch Vibrationen und Stöße hervorgerufen, geeignet. Erfindungsgemäß wird deshalb ein Werkstoff vorgeschlagen, zusammengesetzt aus einem hohen Anteil an Aluminiumoxid sowie Zirkonoxid und Strontiumaluminat.
