· JVASP-42135· PmHoMg2

PmHoMg2 is an intermetallic ceramic compound containing promethium, holmium, and magnesium, representing a rare-earth-based ceramic system. This material belongs to the family of rare-earth intermetallics and appears to be a research or developmental compound rather than an established commercial ceramic. Potential applications would leverage rare-earth ceramics' thermal stability, neutron absorption properties, or specialized electronic/magnetic functionalities, though this specific composition is not widely documented in conventional engineering practice.
