Specifications of black silicon carbide powder

Black silicon carbide powder is an artificial material made by heating quartz sand and oil coke in an electric heater. It has high firmness, sharp edges, and solid thermal conductivity. This makes it ideal for grinding, polishing, and reducing applications. The powder is chemically stable and withstands oxidation at high temperatures. It functions well in rough devices, refractory products, and surface area treatment procedures.

The main chemical structure is silicon carbide (SiC), with a typical web content of 98% or higher. Impurities like totally free carbon, iron, and silicon dioxide are minimal. The Mohs firmness ranges in between 9.2 and 9.5, close to diamond. Fragment sizes vary from crude grits (8-220 mesh) to micro powders (F230-F2000). Customers select sizes based upon details demands. Coarser grains take care of heavy material elimination, while finer powders achieve smooth coatings.

Black silicon carbide has a high melting point of around 2700 ° C. It performs reliably in severe warmth, making it suitable for heating system cellular linings or high-temperature ceramics. Thermal conductivity is about 120 W/m · K, which aids dissipate warm rapidly throughout grinding. This minimizes thermal damage to work surfaces. The product also stands up to acid and alkali corrosion, guaranteeing resilience in severe environments.

Bulk density varies from 1.2 to 1.6 g/cm ³, depending on grain size. Tighter fragment packing enhances density. Low-density powders match applications calling for lightweight abrasives. The product’s brittleness permits it to fracture right into smaller bits throughout usage, maintaining sharp sides for regular performance.

Black silicon carbide powder is packaged in moisture-proof bags or containers. Typical packaging dimensions include 25 kg, 50 kg, and 1-ton options. Personalized product packaging is readily available for bulk orders. Storage space needs a dry, ventilated area to prevent clumping. Shelf life is uncertain if kept covered and devoid of impurities.

The powder is commonly made use of in markets such as vehicle, aerospace, electronics, and construction. Typical applications consist of washing optical lenses, refining metal surface areas, strengthening porcelains, and manufacturing anti-slip coatings. It is cost-efficient contrasted to green silicon carbide, supplying a balance of performance and cost.
