Metallurgical Grade Black Sic Black Silicon Carbide Powder

Metallurgical Grade Black Silicon Carbide (SiC) powder is a high-performance abrasive and metallurgical material widely used in steelmaking, foundry, and casting industries. Characterized by its dark color and sharp, angular grains, this SiC is produced by heating silica sand and petroleum coke in electric arc furnaces at extremely high temperatures.

Typically available in purity levels ranging from 88% to 98%, it offers a cost-effective solution for heavy-duty abrasion and metallurgical applications. The powder form is especially useful in lapping, grinding, and as a raw material for producing refractory products. In metallurgy, it serves multiple roles including deoxidation, slag conditioning, and as an additive to enhance the properties of metal castings. Its hardness, only second to diamond, makes it highly effective for cutting, grinding, and shaping hard materials such as iron, steel, and non-ferrous metals.

Metallurgical grade Black SiC is also employed in the production of bonded and coated abrasives, as well as in the manufacture of refractory bricks and kiln furniture. Its thermal conductivity and resistance to thermal shock further enhance its utility in high-temperature environments. Available in both powder and lump forms, this versatile material meets the demands of foundries, steel mills, and abrasives manufacturers.
