Vanadium Diboride Powder VB2 CAS 12007-37-3

Vanadium Diboride (VB₂) is an ultra-high-performance ceramic material renowned for its exceptional hardness, thermal stability (melting point >2400°C), and electrical conductivity. This gray-black crystalline compound is engineered for extreme environments, offering unmatched durability in aerospace, nuclear, and industrial applications.

Extreme Hardness: Surpasses many borides (e.g., TiB₂) with a hardness of 25 GPa.
Thermal Shock Resistance: Stable under rapid temperature fluctuations (e.g., 20°C to 2000°C cycles).
Oxidation Resistance: Forms protective B₂O₃/V₂O₅ layers at high temperatures.
Lightweight Design: Lower density than traditional refractory metals (e.g., W, Ta).
