· JVASP-99392· Tm3Ge

Tm3Ge is an intermetallic ceramic compound composed of thulium and germanium, belonging to the rare-earth germanide family of materials. This is a research-phase compound studied primarily for its potential in high-temperature applications and electronic/thermal management where rare-earth intermetallics offer tunable properties. While not yet widely deployed in mainstream engineering, materials in this class are of interest for advanced aerospace structures, solid-state cooling devices, and specialized electronic packaging where the combination of ceramic stability and metallic character can be advantageous.
