· JVASP-37569· TmSi3

TmSi3 is an intermetallic ceramic compound composed of thulium and silicon, belonging to the rare-earth silicide family. This material is primarily investigated in research settings for high-temperature structural applications and potential use in advanced thermal management systems, where its chemical stability and refractory characteristics are of interest. Rare-earth silicides like TmSi3 are being explored as alternatives to conventional superalloys in extreme environments, though widespread industrial adoption remains limited compared to established ceramic systems.
