Product Description
Black Silicon Carbide (SiC) is a high-performance abrasive made from silicon quartz sand and petroleum coke, melted at high temperatures in an electric furnace. It forms hexagonal crystals that are extremely hard, sharp, and friable.
Features
1. High Hardness
Mohs hardness of 9.2-9.5, excellent for cutting, grinding, and polishing.
2. Thermal Stability
Maintains structure at high temperatures, suitable for refractory applications.
3. Chemical Resistance
Resistant to oxidation and corrosion, suitable for harsh environments.
4. Electrical Conductivity
Semi-conductive, useful in electronic applications.
5. Cost-Effectiveness
More affordable than other high-performance materials like diamond.
