· JVASP-37465· Tm3Si

Tm₃Si is an intermetallic ceramic compound composed of thulium and silicon, belonging to the rare-earth silicide family. This material is primarily of research interest for high-temperature structural applications, where rare-earth silicides are investigated for their potential to maintain strength and oxidation resistance at elevated temperatures. Tm₃Si and related rare-earth silicides represent an emerging class of ultra-high-temperature ceramics being explored as matrix phases or reinforcement in composite systems, particularly where conventional oxide ceramics may be limited.
