Ta2Cr3Si
metal· 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.
