Ce4B2N5
ceramic· JVASP-34155· Ce4B2N5
Ce₄B₂N₅ is an advanced ceramic compound combining cerium, boron, and nitrogen, belonging to the family of rare-earth boron nitride ceramics. This material is primarily of research and developmental interest, investigated for high-temperature structural applications where its rare-earth content may provide enhanced oxidation resistance and thermal stability compared to conventional boron nitride ceramics. The boron-nitrogen backbone provides inherent ceramic hardness and thermal shock resistance, while the cerium addition offers potential improvements in fracture toughness and sintering behavior—properties valuable in extreme thermal environments.

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.
