NbCoSb is an intermetallic compound combining niobium, cobalt, and antimony, belonging to the half-Heusler alloy family. This is primarily a research material investigated for thermoelectric and high-temperature structural applications due to its favorable mechanical stiffness and thermal properties. While not yet widely deployed in production, half-Heusler compounds like NbCoSb are of interest to materials scientists for next-generation energy conversion and aerospace applications where conventional alloys reach their limits.
