Black Silicon Carbide Refractory Bricks | High-Temperature Strength & Wear Resistance

Unmatched Material Properties:

Black Silicon Carbide is synthesized from quartz sand and petroleum coke, smelted at ultra-high temperatures to produce a material with exceptional characteristics:

• Superior Hardness: Mohs hardness of 9.3, ranking second only to diamond, CBN, and boron carbide among abrasives, ensuring outstanding wear resistance.

• Exceptional High-Temperature Strength: Maintains structural integrity and mechanical strength under extreme heat.

• Excellent Thermal Conductivity & Stability: High thermal conductivity coupled with a low coefficient of thermal expansion provides superior thermal shock resistance.

• Proven Durability: Offers excellent resistance to erosion, corrosion, and abrasion, leading to a longer service life.
