Our group has decades of materials and technological experience and proven expertise in the field of functional materials. Ceramic functional materials with specific processing and application properties form the platform for a large number of innovative components, modules and systems. We have mastered the entire technology chain from material synthesis via various shaping and sintering processes to a contacted component. With the aid of various mixing and dispersing technologies, we can process functional ceramic powders into functional pastes and inks for a wide range of different applications. This is supplemented by our specialized knowledge in the production and processing of nanodisperse powders, both using wet-chemical bottom-up approaches and top-down processes by high-energy milling.

We offer service research and development directly to companies of any size. We also seek cooperation in publicly funded development projects with enterprises and research institutions. We are reliable partners for long-term cooperation in strategic development complexes. And we always remain open for new initiatives to bridge the gap between science and industry.
