· B2 C2

B₂C₂ is an experimental boron-carbon ceramic compound belonging to the family of boron carbides, which are ultra-hard refractory materials. This research-phase material is being investigated for extreme-environment applications where exceptional hardness, thermal stability, and chemical resistance are required, though it remains largely in academic development and has not achieved significant commercial deployment compared to established boron carbide (B₄C) alternatives.
