· JVASP-37377· TmAl3C3

TmAl3C3 is a ternary intermetallic compound combining thulium, aluminum, and carbon, belonging to the rare-earth metal carbide family. This is a research-phase material with limited industrial deployment; it represents the broader class of rare-earth aluminide carbides being investigated for high-temperature structural applications and advanced material systems. The incorporation of thulium provides potential for enhanced refractory performance and specialized functional properties in extreme environments.
