· CeFe3.5Co0.5Sb13

CeFe₃.₅Co₀.₅Sb₁₃ is a rare-earth intermetallic compound belonging to the skutterudite family, where cerium atoms are embedded in a cage-like framework of iron, cobalt, and antimony. This is a research-stage thermoelectric material designed to convert temperature gradients into electrical current, with potential advantages over conventional semiconductors for waste heat recovery in extreme environments. The material is notable for its potential in solid-state energy conversion applications where traditional thermoelectrics cannot operate reliably at high temperatures or in corrosive conditions.

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.
