· JVASP-116642· TaVSi4

TaVSi4 is a refractory intermetallic compound combining tantalum, vanadium, and silicon, belonging to the family of high-temperature metal silicides. This is primarily a research and development material investigated for extreme thermal and oxidation environments where conventional superalloys reach their limits. Industrial interest centers on aerospace and energy applications requiring materials that maintain strength and oxidation resistance at very high temperatures, though adoption remains limited pending further optimization of processing, cost, and reproducibility.

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.
