· Tm3GaC

Tm3GaC is a ternary ceramic compound belonging to the MAX phase family, composed of thulium, gallium, and carbon. This material is primarily investigated in research contexts for its potential in high-temperature structural applications, leveraging the characteristic damage tolerance and electrical conductivity of MAX phases that distinguish them from conventional brittle ceramics. While not yet established in volume production, Tm3GaC and related rare-earth MAX phases are explored for aerospace, nuclear, and thermal management applications where materials must withstand extreme temperatures and thermal cycling.
