5 FAQs of SIC Silicon Carbide Black Silicon Carbide Powder Fine Powder

What is Silicon Carbide (SiC) Black Silicon Carbide Powder?
Silicon Carbide (SiC) is a synthetic compound made from silica sand and carbon at high temperatures. Black Silicon Carbide Powder is a fine-grade variant known for its extreme hardness (9.5 Mohs), thermal stability, and chemical resistance. It’s widely used in abrasive applications, refractories, and advanced ceramics due to its durability and ability to maintain performance under extreme conditions.

What are the primary applications of Fine Black Silicon Carbide Powder?
This powder is used in grinding, polishing, and lapping processes for metals, glass, and ceramics. It’s also a key material in refractory linings for high-temperature furnaces, semiconductor manufacturing for wafer slicing, and as an additive in composites to enhance strength and wear resistance. Its electrical conductivity makes it suitable for electronic components like resistors and heating elements.

What is the particle size range of Fine Black Silicon Carbide Powder?

Consistency in particle distribution ensures uniform performance in tasks like surface finishing or composite reinforcement.

Is Black Silicon Carbide Powder safe to handle?
While non-toxic, the fine powder poses inhalation risks. Use protective gear (masks, gloves) and ensure proper ventilation during handling. Avoid direct skin contact to prevent irritation. Store in a dry, cool area away from moisture and incompatible chemicals. Follow OSHA or local safety guidelines for industrial use.

How does Black Silicon Carbide differ from Green Silicon Carbide?
Black SiC is slightly less pure (98% SiC) but tougher, ideal for grinding hard, non-ferrous materials. Green SiC (99%+ purity) is sharper and more brittle, suited for precision polishing of semiconductors or ceramics. Black SiC is more cost-effective for general industrial use, while green is reserved for high-precision applications.
