· JVASP-56258· PmMg

PmMg is a ceramic intermetallic compound composed of promethium and magnesium, representing an experimental material of primarily academic and nuclear research interest rather than established commercial engineering use. This compound belongs to the rare-earth intermetallic ceramic family and is notable for combining a radioactive lanthanide element (promethium) with a lightweight metal matrix, making it relevant to specialized nuclear materials science and potential radioisotope applications where material stability under radiation is critical. Due to promethium's short half-life and restricted availability, practical engineering applications remain limited to research contexts, though the magnesium-lanthanide intermetallic class shows promise for high-temperature structural applications and radiation-resistant material design.
