Be₂B is a beryllium boride ceramic compound that belongs to the family of hard, lightweight refractory ceramics. This material is primarily of research and development interest rather than established industrial production, investigated for applications demanding exceptional stiffness combined with low density. Its potential utility centers on aerospace and defense sectors where weight reduction and thermal stability are critical, though commercial adoption remains limited due to beryllium's toxicity concerns, manufacturing complexity, and cost.
