· JVASP-21001· Ta6Si7Ni16

Ta6Si7Ni16 is an intermetallic compound combining tantalum, silicon, and nickel, belonging to the family of high-temperature metal silicides and intermetallics. This material is primarily of research and developmental interest rather than established industrial production, being studied for applications requiring exceptional thermal stability and oxidation resistance at elevated temperatures. The tantalum-rich composition suggests potential use in aerospace and high-performance thermal applications where conventional superalloys reach their limits.
