LIquid Metal Competence center Karlsruhe (LIMCKA)

Flüssigmetall-Kompetenzzentrum des KIT

The research at KIT on liquid metals as a heat transfer medium in energy and process technology combines scientific work on thermal hydraulics and technology development in a unique and comprehensive manner with liquid metal-specific material research and materials development. Our vision is to strengthen and expand on this basis the national and international leading position of KIT liquid metal research. The current and future topics are embedded in several major strategic projects and projects.
