Black silicon carbide (SiC) is a semi-friable abrasive often used for general abrasive appliions in bonded abrasive tools, lapping, polishing, tock tuling, glass etching and frosting. Black Silicon Carbide grains for bonded appliions. Used in the manufacture of grinding wheels, polishing blocks, rubbing bricks, honing sticks, foundry fluxes, rice and dal-mill, shellers, for …

-6-29 · Green silicon carbide powder is made of high quality large crystalline green silicon carbide by crushing, vertical ball mill particle shaping, pickling water, hydraulic precision classifiion, natural sedimentation and high temperature drying. Characteristics. 1.High hardness. 2.High wear resistance. 3.High corrosion resistance

Silicon carbide grains are sharper and harder than aluminum oxide grains, but silicon carbide is less durable than aluminum oxide. Silicon carbide is best for non-metallic or low tensile strength materials, while aluminum oxide works best on materials with high tensile strengths. Both can be coined to produce a finer, smoother abrasive cut ...

Pure silicon carbide can be made by the so-called Lely process, in which SiC powder is sublimated into high-temperature species of silicon, carbon, silicon dicarbide (SiC2), and disilicon carbide (Si2C) in an argon gas aient at 2500 °C and redeposited into flake-like single crystals,sized up to 2×2 cm, at a slightly colder substrate.
