HfCoSb is a ternary intermetallic compound combining hafnium, cobalt, and antimony, belonging to the family of half-Heusler alloys. This material is primarily of research and development interest for thermoelectric applications, where its electronic and thermal transport properties make it a candidate for solid-state energy conversion devices operating at elevated temperatures. HfCoSb and related half-Heusler compounds are being investigated as alternatives to traditional thermoelectric materials in power generation and waste heat recovery systems, offering potential advantages in thermal stability and performance in high-temperature industrial environments.
