· Ce1 Fe4 As12

CeFe₄As₁₂ is a rare-earth iron arsenide compound belonging to the filled skutterudite family of semiconductors, characterized by a cage-like crystal structure with cerium atoms enclosed within an iron-arsenic framework. This material is primarily of research interest for thermoelectric applications, where the rattling behavior of the rare-earth atom within the structure can reduce thermal conductivity while maintaining electrical conductivity—a desirable combination for waste-heat recovery and power generation. CeFe₄As₁₂ represents an experimental compound being investigated as an alternative to traditional Bi₂Te₃-based thermoelectrics, though it remains largely in academic development rather than established industrial production.

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.
