· FeSb2

FeSb₂ is an iron antimonide intermetallic compound belonging to the transition metal pnictide family. This material is primarily of research interest for thermoelectric applications and magnetism studies, where its electronic band structure and potential for phonon scattering make it a candidate for thermal energy conversion systems. While not yet commercialized at scale, iron antimonides are explored as alternatives to more established thermoelectric materials, with particular focus on mid-temperature range power generation and waste heat recovery applications where cost and element abundance offer advantages over rare-earth based competitors.

Export Control

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.
