· JVASP-17878· ErTiSi

ErTiSi is an intermetallic compound combining erbium, titanium, and silicon—a research-phase material belonging to the rare-earth transition metal silicide family. This material class is investigated for high-temperature structural applications where improved stiffness and thermal stability over conventional titanium alloys are sought. ErTiSi and related rare-earth silicides remain largely experimental, with potential interest in aerospace and energy sectors where materials must maintain strength at elevated temperatures, though industrial adoption has not yet been established.
