· Fe4 Sb12 Nd1

Fe4 Sb12 Nd1 is a rare-earth-filled skutterudite compound, a class of intermetallic semiconductors where neodymium atoms occupy cage-like voids within an iron-antimony framework. This material is primarily of research interest for thermoelectric applications, where the rattling behavior of the rare-earth filler atoms reduces thermal conductivity while maintaining electrical conductivity, making it attractive for waste heat recovery and solid-state cooling devices. Skutterudites represent a promising alternative to traditional thermoelectric materials due to their potential for high ZT (figure of merit) values, though Fe4 Sb12-based compounds remain largely in development and commercialization faces challenges related to material stability and cost.

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.
