TaVSi4
metal· 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.
