ceramic

· JVASP-39024· Tm5Sb3

Tm₅Sb₃ is an intermetallic ceramic compound composed of thulium and antimony, belonging to the rare-earth pnictide family of materials. This is primarily a research-phase material studied for its electronic and thermal properties rather than a production engineering ceramic. The thulium-antimony system is of interest in solid-state physics and materials research for potential applications in thermoelectric devices, semiconductor research, and high-temperature stability studies, though industrial adoption remains limited compared to established ceramic and intermetallic alternatives.
