In this issue, we focus on high-performance ceramics and their potential applications in the fields of energy and environmental technology. We find that the areas of application are just as diverse as the properties of this extraordinary material. It is particularly wear-resistant, and even high temperatures and corrosive media cannot affect it. This makes high-performance ceramics an irreplaceable component of electric cars. In the form of piezoceramic sensors, insulating components or as plain bearings, but also in the thermal management of power electronics, ceramics play an important role. …
