· JVASP-22426· Yb2C3

Yb2C3 is a rare-earth carbide ceramic composed of ytterbium and carbon, belonging to the family of refractory carbides used in extreme-temperature and high-performance applications. While primarily an experimental and research material, ytterbium carbides are investigated for potential use in aerospace thermal protection systems, nuclear fuel cladding, and high-temperature structural components where resistance to oxidation and thermal shock is critical. These materials represent an emerging class of ultra-high-temperature ceramics, offering advantages over conventional carbides in specific niche applications where rare-earth properties provide enhanced performance.

Regulatory Screening

Environmental

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.
