· 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.
