· JVASP-22277· Tb2Si5Ru3

Tb2Si5Ru3 is an intermetallic ceramic compound combining terbium, silicon, and ruthenium—a research-phase material developed for high-temperature structural applications. This compound belongs to the family of rare-earth silicide-based ceramics, which are investigated for their potential to operate in extreme thermal environments where conventional ceramics or superalloys face limitations. While not yet in widespread industrial production, materials in this composition space are of interest for aerospace propulsion systems, nuclear reactor components, and other applications demanding thermal stability combined with oxidation resistance.
