Electroceramics for Electrical and Electromechanical Applications
Electroceramic materials combine the distinctive properties of technical ceramics with electrical, dielectric, and electromechanical functions. They are used in applications including sensors, actuators, transducers, as well as RF and high-voltage capacitors.
CeramTec develops and manufactures electroceramic solutions for demanding industrial applications – ranging from piezoelectric components to ceramic dielectrics and capacitors.
What Are Electroceramics?
Electroceramics are ceramic materials and components that are specifically used in electrical engineering and electronics due to their electrical, dielectric, piezoelectric, or electromechanical properties.
Depending on their composition, microstructure, and processing, ceramics can, for example, provide electrical insulation, store electrical energy, or convert mechanical energy into electrical energy and vice versa. This makes electroceramics suitable for applications requiring reliable performance, high precision, compact designs, or operation under demanding environmental conditions.
At CeramTec, two solution areas are of particular importance: piezoceramics for sensors, actuators, and transducers, as well as dielectric ceramics for RF and high-voltage capacitors.
| Technology | Function |
|---|---|
| Piezoceramics | Converts mechanical loads into electrical signals – and electrical energy into motion or vibration. |
| Dielectric Ceramics | Supports electrical insulation and energy storage in ceramic capacitors. |
Materials Expertise and Customized Solutions
Electroceramic components are defined not only by their shape, but above all by the properties of the material used. Composition, microstructure, electrical characteristics, temperature behaviour, geometry, and processing must be tailored to the specific application.
CeramTec supports customers in selecting suitable ceramic materials and developing application-specific components. From material selection and design through to manufacturing, technical requirements can be taken into account at an early stage.
