Black Silicon Carbide For Bonded Abrasive
Black Silicon Carbide (CAS: 409-21-2), also known as carborundum,
it ensures fast material removal and precise finishing in abrasive tools.
Available in durable 25kg bags or bulk 1-ton bags for secure storage
Ideal for grinding wheels, cutting discs, and abrasive tools due to its durability and consistent performance.
- Product Introduction
Products Description
Black silicon carbide is a high-performance abrasive material produced by smelting high-purity quartz sand and petroleum coke in an electric resistance furnace at extreme temperatures. Known for its exceptional hardness-second only to diamond-it exhibits a unique combination of brittleness, sharpness, and moderate thermal/electrical conductivity. These properties make it ideal for demanding applications such as grinding, sandblasting, precision polishing, surface preparation, and specialized abrasive tools like grinding wheels, sandpaper, and cutting discs. Additionally, it serves as a key material in refractory coatings, foundry molds, and high-strength flooring systems.
Key Characteristics:
Superior Hardness: Near-diamond level, ensuring aggressive material removal.
Chemical Stability: Resists reactions with acids, alkalis, and extreme temperatures.
High Thermal Conductivity: Efficient heat dissipation during high-intensity operations.
Low Thermal Expansion: Maintains dimensional stability under thermal stress.
Enhanced Toughness: Higher impact resistance compared to green silicon carbide, suitable for brittle materials like glass, ceramics, stone, and non-ferrous metals.
