MoB2 Molybdenum Diboride Powder CAS 12007-27-1

Molybdenum Diboride (MoB₂) is a high-performance refractory ceramic renowned for its exceptional hardness, thermal stability (melting point >2100°C), and metallic conductivity. This dark gray crystalline compound combines molybdenum’s high-temperature strength with boron’s hardness, making it ideal for aerospace, industrial machinery, and advanced electronics requiring extreme durability and reliability.

Ultra-High Hardness: Superior wear resistance in abrasive and high-stress environments.
Thermal Stability: Maintains mechanical integrity up to 1600°C in inert atmospheres.
Oxidation Resistance: Forms protective MoO₃/B₂O₃ layers at elevated temperatures (>800°C).
Cost-Effective: More economical than tungsten-based borides (e.g., WB₂) with comparable performance.
