Black silicon carbide is made by electrofusing quartz sand and petroleum coke at high temperatures in an electrical resistance furnace. Compared with its green counterpart made with similar materials but enhanced with anthracite to create its signature green hue, black silicon carbide offers superior thermal properties.
Ideal applications of this material include bonding and coating applications for lapping and polishing applications as well as pressure blasting applications. Refractory materials and precision ceramics also benefit from its use.
Superior Hardness
Black silicon carbide is one of the world’s hardest abrasives, rivaling even diamond in hardness rating. Its Mohs hardness rating exceeds other conventional abrasives such as aluminum oxide. Due to its exceptional strength, coupled with its cutting action and angularity, black silicon carbide makes an efficient material suitable for use in metalworking, stone processing and automotive/aerospace industries – ideal for sandblasting/grinding applications in these sectors.
As part of the manufacturing process of black silica, high-purity silica sand and petroleum coke are heated at extreme temperatures in an electrical resistance furnace to facilitate chemical reactions between silicon and carbon, leading to silicon carbide formation. After which it is ground down to various grain sizes and shapes suitable for various industrial uses.

Hög värmeledningsförmåga
Black silicon carbide is an advanced abrasive material designed to deliver optimal balance of hardness and thermal conductivity for many industrial applications. Available in standard FEPA sizes as well as custom particle size distributions, densities, chemistries for both macro-grit sizing as well as microgrit sizing; its production involves heating silica sand combined with carbon sources (usually petroleum coke) to extremely high temperatures in an open-hearth “Acheson” furnace until an ideal crystalline formation forms both green or black in color depending on purity of product.
Black silicon carbide’s exceptional hardness and strength make it well suited for grinding and cutting, such as producing abrasive wheels, tools, or sandpaper. Furthermore, its chemical inertness, wear resistance, thermal conductivity, and thermal capacitance all make it highly desirable as a material choice for production purposes.
Due to its exceptional stability and low coefficient of expansion at elevated temperatures, black silicon carbide is frequently utilized as a raw material in the manufacturing of advanced ceramics and refractories. In particular, its use as an inert material for furnace linings, kiln furniture and crucibles makes this material particularly suitable.
Due to its temperature stability and thermal conductivity, glass is an ideal material for producing mirrors for astronomical telescopes such as Herschel Space Telescope. Furthermore, due to its low expansion rate and hardness it makes an excellent material choice for use in electrical power generators as they can withstand the high mechanical loads present when dealing with high voltage equipment.
Hög motståndskraft mot slitage
Black silicon carbide’s extreme hardness allows it to resist wear, making it suitable for harsh environmental conditions that would easily destroy less robust materials. Furthermore, its thermal conductivity assists with dissipating heat across components to keep them cool and prevent overheating – an attribute which makes it popular choice in ceramics and refractories applications, ceramic kilns and refractories production; its resistance to high-temperature thermal shock makes it especially valued within aerospace and automotive industries where seals and bearings must endure sudden temperature changes without damage or failure.
Abrasives: Black silicon carbide powder is widely used for producing grinding wheels, cutting discs and other abrasive tools due to its exceptional sharpness and hardness. Furthermore, its wear-resistance provides it with an edge over aluminum oxide or diamond products.
Black silicon carbide is an extremely dense material with low expansion and contraction rates, which allows it to retain its shape under stress, making it perfect for high performance applications such as manufacturing refractory materials or precision ceramics. Furthermore, its pressure tolerance withstands pressure at high temperatures without cracking, making it an asset when used in rocket nozzle applications; additionally its inertness is an asset when applied chemical environments.
