ceramic

· JVASP-35793· PmN

PmN is a ceramic compound based on promethium nitride, a rare-earth nitride ceramic belonging to the family of refractory and high-hardness ceramics. This material is primarily of research and theoretical interest rather than established industrial production, as promethium is a synthetic radioactive element with limited availability. PmN is studied for potential applications in extreme-environment engineering, nuclear systems, and high-temperature structural applications where its ceramic hardness and refractory character could provide value, though practical deployment remains constrained by material sourcing and the radiological properties inherent to promethium-based compounds.
