Black Silicon Carbide Green Silicon Carbide for Refractory Abrasives Material
Black Silicon Carbide (SiC) and Green Silicon Carbide are two high-performance abrasive materials widely used in refractory and abrasive applications, each offering unique properties suited for specific industrial needs. Black SiC, produced from silica sand and petroleum coke, is the more economical variety, ideal for general-purpose grinding, cutting, and refractory applications. It features a sharp, angular structure and is highly effective for working with metals, ceramics, stone, and glass.
Green SiC, on the other hand, is made from a higher-purity mixture, including silicon dioxide and petroleum coke with better carbon sources, giving it a lighter color and greater hardness. It is often used in precision abrasives and applications requiring higher purity, such as semiconductor and optical material polishing. Both types are widely utilized in the production of bonded abrasives (like grinding wheels), coated abrasives, and refractory materials such as kiln furniture, furnace liners, and crucibles.
Their exceptional hardness, only second to diamond, ensures efficient material removal and extended tool life. Black SiC is typically chosen for general metallurgy and heavy-duty abrasion, while Green SiC is preferred for high-precision and high-purity applications. Together, they provide a comprehensive solution for industries requiring durable, thermally stable, and chemically resistant abrasive and refractory materials. Whether used in metalworking, ceramics, or refractory manufacturing, Black and Green Silicon Carbide deliver unmatched performance and versatility.
