· LaFe3CoSb12

LaFe3CoSb12 is a rare-earth filled skutterudite compound, an intermetallic material where lanthanum atoms occupy cage-like voids within a transition metal-antimony framework. This is a research-stage thermoelectric material being investigated for solid-state heat-to-electricity conversion and refrigeration applications, where its low thermal conductivity combined with electrical properties makes it a candidate for next-generation thermoelectric devices operating in mid-temperature ranges (typically 300–700 K).

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.
