· TmCuPb

TmCuPb is a ternary intermetallic compound containing thulium, copper, and lead. This is a research-phase material studied primarily in solid-state chemistry and materials science for its structural and electronic properties rather than a material with established industrial applications. The thulium-copper-lead system is of interest for fundamental investigations into rare-earth intermetallic phases, with potential relevance to thermoelectric or magnetic applications if suitable properties are demonstrated.
