Piezoceramics & Piezo Technology
How can mechanical forces be converted into precise electrical signals in real time, and electrical signals into controlled mechanical movement? This is where CeramTec piezoceramics come into play. As key functional components in modern sensors and actuators, they enable highly accurate measurement, monitoring and control across medical technology, automotive applications, energy systems and industrial manufacturing.
Whether you need individual piezoceramic components or fully assembled, ready-to-use products, CeramTec is your reliable development partner. From material selection and component design to application-specific development and manufacturing, we work closely with you to turn your requirements into high-performance piezoceramic solutions.
CeramTec at COMPAMED 2026
From November 16 to 19, 2026, visit us at Stand L31 in Hall 8B to discover our solutions for demanding medical equipment applications. Key areas of focus include structural ceramics, lead-free piezoceramics, ultrasound technologies, additive manufacturing, and hermetic sealing solutions.
Lead-free Piezoceramics
We create added value for manufacturers of industrial and medical products with customised solutions that represent a sensible alternative to lead-containing materials. Our lead-free ceramic components based on BNT-BT can be manufactured in various shapes and geometries - depending on your requirements, e.g. as sensors or transducers for flow meters or medical applications.

Piezoceramics Explained
In this video, we provide an insight into the operating principle and the wide range of applications of piezoceramics at CeramTec. Using specific examples, we show how piezoceramic solutions support engine management in cars, regulation in air-source heat pumps and the stabilization of solar panels on satellites.
RoHS Directive
RoHS: Directive on the Restriction of the use of certain Hazardous Substances in electrical and electronic equipment.
This directive describes the avoidance of hazardous or harmful substances in electrical or electronic equipment. CeramTec's Multifunctional Ceramics Division sells ceramic components and is therefore not directly affected by this directive - but our customers may be. The main component of piezoceramic components are lead compounds such as lead zirconate and lead titanate. Unfortunately, this is unavoidable. This is also the view of the European Commission. This is why, for example, lead compounds in ceramic compounds are exempt from the ban in the "End-of-Life Vehicle Regulation".
Despite this, or precisely because of this, we want to support our customers in this respect: CeramTec offers to take back piezoceramic components and to dispose of them in an environmentally friendly way or to recycle them. The prerequisite is that the piezoceramics are delivered without foreign components (i.e. not in the housing or cast in). If you are interested in recycling, please contact us. We will be happy to make you an offer.
Another step towards RoHS conformity is the development of the lead-free piezoceramic special material SONOX® P1 LF by CeramTec.
