VCoSb
metal· VCoSb
VCoSb is a ternary intermetallic compound belonging to the half-Heusler alloy family, combining vanadium, cobalt, and antimony. This material is primarily of research interest for thermoelectric applications, where it is investigated for its potential to convert waste heat into electrical power in moderate-temperature ranges. While not yet widely deployed in high-volume production, half-Heusler alloys like VCoSb are notable candidates for next-generation thermoelectric devices and waste-heat recovery systems due to their tunable electronic and thermal properties and relative abundance of constituent elements compared to traditional thermoelectric materials.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
