Ta3V7Si6
metal· JVASP-145349· Ta3V7Si6
Ta3V7Si6 is a refractory intermetallic compound combining tantalum, vanadium, and silicon—elements known for high melting points and oxidation resistance. This is an experimental/research-phase material studied for ultra-high-temperature structural applications where conventional superalloys reach their limits. The material belongs to the family of transition metal silicides and vanadium-based intermetallics, which are investigated for aerospace engines, hypersonic vehicle structures, and extreme-environment components where thermal stability and strength must be maintained above 1000°C.
