· JVASP-116643· Ta2Cr3Si

Ta2Cr3Si is a ternary intermetallic compound combining tantalum, chromium, and silicon—a refractory metal system designed for extreme-temperature and wear-resistant applications. This material belongs to the family of high-entropy and refractory intermetallics under active research for aerospace and energy sectors, where its tantalum content provides oxidation resistance and the silicide phase contributes hardness and thermal stability. While primarily a research compound rather than a commodity material, Ta2Cr3Si and related ternary systems show promise for applications demanding simultaneous strength at elevated temperature and resistance to thermal cycling and chemical attack.

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.
