· JVASP-40855· NaPmHg2

NaPmHg2 is an experimental ceramic compound containing sodium, promethium, and mercury—a rare-earth hybrid material that exists primarily in research contexts rather than established commercial production. This material family is investigated for specialized applications requiring unique combinations of mechanical properties and potential functional characteristics derived from rare-earth and mercury chemistry. Due to its experimental status and the radiological properties of promethium-147, practical deployment remains limited to controlled laboratory and potential medical/industrial research environments.
