· 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.

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.
