· JVASP-36410· BeB2

BeB₂ is an experimental ceramic compound composed of beryllium and boron, belonging to the ultra-hard ceramic family alongside boron carbide and similar refractory materials. While not yet commercialized at scale, this material is investigated in research contexts for extreme-environment applications where high hardness, low density, and thermal stability are critical—positioning it as a potential alternative to conventional ceramics in aerospace and defense sectors where weight and performance at elevated temperatures are competing demands.
