5 FAQs of Emery Sand Black Silicon Carbide Carborundum Grit Grain Silicon Carbide Powder Ton

What is Emery Sand Black Silicon Carbide Carborundum Grit Grain Silicon Carbide Powder?
Emery Sand Black Silicon Carbide (SiC) is a synthetic abrasive material produced by heating silica sand and carbon at high temperatures. Known for its extreme hardness (9.5 Mohs), thermal conductivity, and durability, it’s used for grinding, cutting, polishing, and surface preparation. Its black color comes from impurities like iron during manufacturing, making it cost-effective for industrial applications.

What are the primary applications of Black Silicon Carbide?
Black Silicon Carbide is widely used in abrasive blasting, grinding wheels, sandpaper, and refractory materials. It’s ideal for processing non-ferrous metals, glass, ceramics, and stone due to its sharp edges and hardness. It also serves as an additive in coatings, electronics, and automotive parts for heat resistance and wear protection.

What is the difference between grit, grain, and powder forms?
Grit and grain refer to coarser particles (typically 8-220 mesh) used for heavy-duty tasks like grinding or cutting. Powder consists of finer particles (up to 3000 mesh) for polishing, lapping, or precision surface finishing. The choice depends on the required finish—coarser grits remove material faster, while powders deliver smooth, refined results.

Is Black Silicon Carbide safe to handle?
While non-toxic, inhalation of fine particles can irritate the respiratory system. Use PPE like masks, gloves, and goggles during handling. Store in a dry, ventilated area to prevent moisture absorption, which can reduce effectiveness. Avoid direct skin contact to prevent irritation.

How is Black Silicon Carbide packaged when sold by the ton?
It’s typically packed in 25-50 kg woven bags with moisture-proof liners or bulk super sacks for large orders. Custom packaging (e.g., palletized, labeled) is available. Ensure suppliers comply with industry standards for consistent particle size and purity. One ton equals approximately 20-40 bags, depending on bag size, optimized for logistics and storage efficiency.
