ceramic

· JVASP-37769· PmSmHg2

PmSmHg2 is an intermetallic ceramic compound containing promethium, samarium, and mercury—a rare-earth based material that exists primarily in research contexts rather than established commercial production. This compound represents exploration within the rare-earth intermetallic family, where such phases are investigated for potential applications in high-density systems, magnetic materials, or specialized electronic applications, though industrial deployment remains limited due to the scarcity and radioactivity of promethium and the volatility of mercury at elevated temperatures.
