Cobalt Monoboride (COB) Powder Cobalt Boride CAS 12006-77-8

Cobalt Monoboride (CoB) is a high-performance intermetallic compound known for its exceptional hardness, thermal stability (melting point >1500°C), and catalytic properties. This gray-black crystalline material combines cobalt’s magnetic and corrosion-resistant traits with boron’s hardness, making it ideal for industrial machinery, chemical catalysis, and advanced electronics.

High Hardness: Superior wear resistance in abrasive environments.
Thermal Stability: Retains structural integrity up to 1000°C in inert atmospheres.
Corrosion Resistance: Stable in acidic and alkaline conditions (pH 3–11).
Catalytic Efficiency: Enhanced surface activity for industrial chemical processes.
