Black silicon carbide is a high-performance industrial material renowned for its exceptional hardness and durability. As a key player in the abrasives and refractory sectors, it serves B2B buyers seeking reliable solutions for manufacturing and processing needs.
Green Silicon Carbide (SiC) is a high-purity crystalline abrasive material produced by smelting high-quality silica sand and petroleum coke with a small amount of salt in an electric resistance furnace. With a Mohs hardness of 9.4, it is second only to diamond, making it ideal for ultra-precision grinding and cutting applications that demand extreme hardness and sharpness.
This material is composed mainly of pure silicon and carbon atoms, forming a strong covalent lattice that results in outstanding thermal conductivity, chemical inertness, and superior wear resistance. Unlike Black Silicon Carbide, Green SiC is more friable, allowing it to self-sharpen during use—critical for maintaining consistent surface finishes in precision applications.
Green Silicon Carbide is widely used in industries such as solar wafer cutting, semiconductor processing, ceramics grinding, optical polishing, and fine abrasives manufacturing. Its low iron content and high-temperature stability make it suitable for use in clean rooms and advanced technical environments.
Green Silicon Carbide stands out for its ultra-high purity and sharp friable crystal structure, making it the material of choice for applications that require precision, minimal contamination, and a consistent surface finish. Manufactured by smelting silica and petroleum coke with added salt at high temperatures, it achieves a purity of over 99%, surpassing most conventional abrasives in performance and cleanliness.
Its grain structure is more friable than Black Silicon Carbide, allowing continuous self-sharpening under pressure, which leads to uniform material removal and less heat generation. This makes it ideal for sensitive grinding tasks such as wafer slicing, glass polishing, and fine ceramics processing.
Green SiC also boasts excellent thermal and chemical stability, enabling it to maintain performance in both corrosive and high-temperature conditions without structural degradation.
Compared to other abrasive materials like Black Silicon Carbide or White Fused Alumina, Green Silicon Carbide stands out for its ultra-high purity, sharper grain structure, and superior performance in high-precision and contamination-sensitive environments. It is especially well-suited for tasks requiring consistent finishes, such as optical grinding, wafer slicing, and semiconductor processing.
While Black Silicon Carbide is tougher and more cost-effective for general grinding, Green SiC offers better friability and cleaner cutting, which are essential for delicate or micro-scale operations. In contrast to White Fused Alumina, Green SiC is harder and more thermally stable, enabling its use in more aggressive processing conditions.
For manufacturers and technical buyers, these advantages translate into better process stability, fewer defects, and improved product quality across precision-driven industries.
Green Silicon Carbide is manufactured to meet stringent global standards such as ISO and FEPA, with ultra-high purity levels ideal for critical applications in the electronics, photovoltaic, and precision machining industries. Its sharp, friable crystalline structure and thermal stability make it a top choice for processes that require fine finishing and minimal contamination.
Chemically, Green SiC typically contains ≥99% pure silicon carbide with very low levels of free carbon and iron. It offers a Mohs hardness of 9.4, slightly harder than Black SiC, and a bulk density ranging from 1.40 to 1.60 g/cm³ depending on grain size and processing. These attributes allow it to maintain cutting precision and thermal resistance even in demanding cleanroom and high-speed machining settings.
Green SiC is available in a wide spectrum of grit sizes, from coarse to ultra-fine micropowders, including FEPA F-series, JIS, and P-series equivalents. Standard packaging includes 25kg woven bags and 1-ton jumbo bags to ensure safe international transport and bulk availability for industrial buyers.
