metal

· JVASP-17647· CeFeSi

CeFeSi is an intermetallic compound combining cerium, iron, and silicon—a representative member of rare-earth transition metal silicides. This material family is primarily explored in research and high-temperature applications where conventional alloys reach their limits, particularly for thermal management, catalysis, and specialized aerospace or nuclear contexts where rare-earth elements provide enhanced oxidation resistance or unique electronic properties.

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.
