· CeFe3.5Co0.5Sb14

CeFe3.5Co0.5Sb14 is a rare-earth filled skutterudite intermetallic compound, a synthetic material engineered for thermoelectric energy conversion applications. This is an experimental research material in the skutterudite family, where cerium atoms occupy cage-like voids in an iron-cobalt-antimony framework; such compounds are investigated for solid-state heat-to-electricity conversion and waste heat recovery in both terrestrial and space power systems. Skutterudites like this are valued for their potential to achieve high thermoelectric figures of merit at moderate-to-high temperatures, making them candidates for automotive exhaust recovery, radioisotope thermoelectric generators (RTGs), and industrial process heat capture, though practical adoption remains limited compared to bismuth telluride and lead telluride alternatives.

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.
