· Sm2 B4 C4

Sm₂B₄C₄ is a ternary ceramic compound combining samarium (a rare-earth element), boron, and carbon into a single-phase material. This is a research-stage compound within the broader family of rare-earth borocarbides, which are being investigated for high-temperature structural applications and specialized electronic properties. The material's potential lies in extreme-environment applications where conventional ceramics or metals fall short, though industrial adoption remains limited and applications are primarily in academic research and advanced materials development.
