· JVASP-18139· Nd3AlN

Nd₃AlN is an intermetallic nitride compound combining rare-earth neodymium with aluminum and nitrogen, representing an emerging class of materials in the refractory and high-performance ceramics family. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in high-temperature structural components, wear-resistant coatings, and advanced ceramics where the combination of rare-earth strengthening and nitride hardness could provide benefits over conventional alternatives. Its notable characteristics stem from the rare-earth element contribution to thermal stability and the nitride phase's inherent hardness, making it relevant for extreme-environment applications where conventional nickel superalloys or standard alumina ceramics reach performance limits.
