· JVASP-18351· TmBi

TmBi is a rare-earth bismuth intermetallic ceramic compound combining thulium (Tm) and bismuth (Bi) elements. This material belongs to the family of rare-earth pnictide ceramics, which are primarily investigated for their potential in solid-state physics and materials research rather than established commercial applications. The compound is notable within the research community for its electronic and thermal properties, making it relevant for exploratory work in thermoelectric devices, semiconducting ceramics, and fundamental studies of rare-earth intermetallic behavior, though it remains largely in the laboratory development stage.
