· 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.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
