· JVASP-91692· TmCuSb2

TmCuSb2 is an intermetallic compound composed of thulium, copper, and antimony, belonging to the rare-earth-based metal family. This material is primarily of research interest for thermoelectric applications, where it is investigated for its potential to convert thermal energy into electrical energy—a capability driven by its electronic and phonon transport properties. While not yet in widespread industrial production, TmCuSb2 represents the broader class of rare-earth skutterudite and half-Heusler compounds being explored as next-generation thermoelectric materials for waste heat recovery and solid-state cooling systems.

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.
