· JVASP-112672· La3Si7Ni3

La₃Si₇Ni₃ is an intermetallic compound combining lanthanum, silicon, and nickel, belonging to the rare-earth transition metal silicide family. This is primarily a research material of interest for high-temperature applications and functional properties rather than a widely commercialized engineering alloy. The material family is explored for potential use in advanced thermal management systems, catalytic applications, and specialized high-temperature structural components where rare-earth strengthening and intermetallic bonding offer advantages over conventional superalloys.
