Pm2CoIr

Pm2CoIr is a ternary intermetallic compound combining promethium, cobalt, and iridium. This is a research-phase material studied primarily for its potential in high-temperature and corrosion-resistant applications, belonging to the family of rare-earth transition metal alloys. Due to promethium's radioactive nature and limited availability, this material remains largely experimental; its engineering relevance would be in specialized aerospace, nuclear, or advanced catalytic applications where its unique electronic and thermal properties could provide advantages over conventional superalloys or noble metal composites.
