Black SiC and Green SiC are both hard and tough abrasion materials in the industrial field.  Besides the color difference, there are many differences in properties and performance.

Black silicon carbide is an excellent refractory material. It is widely used as a furnace lining, kiln furniture, firebrick, and crucibles.

Green silicon carbide abrasive powder is a brittle & extreme hardness (Mohs hardness of 9.5) material. It is suitable for producing grinding wheels for processing hard and brittle material workpieces. GC F36-F500 are mostly used for Abrasive tools. For example, resin-bonded stone GC grinding wheels; Ceramic grinding wheels for bearing processing; Fiber wheels, wire drawing wheels, flexible grinding wheels, nylon grinding wheels, etc. used for polishing and polishing stone and marble.

There are differences between Black silicon carbide F-Grit and P-Grit in many aspects. Black silicon carbide P-Grit abrasive powder is specifically used in coated abrasives. For example, black silicon carbide water sanding paper, sanding sheets, sponge polishing blocks, nylon polishing wheels, non-woven grinding wheels, black diamond polishing wheels, grid grinding wheels, and other polishing products, these products use black silicon carbide P-Grit grain. Black silicon carbide F-Grit is used for bonded abrasive tools such as resin grinding wheels, diamond grinding wheels, oxalic acid Frankfurt grinding blocks, etc.

Black silicon carbide powder is a fine powder produced from water washing and acid washing process. It has high refractory temperature, high hardness, low thermal expansion coefficient, high thermal conductivity, strong grinding ability, and stable physical and chemical properties. The hardness is higher than that of corundum. And lower than that of green silicon carbide, boron carbide, and diamond. Black carborundum powder has a wide range of applications in fields such as grinding tools, energy, wear resistance, functional ceramics, grinding, refractory materials, etc.
