Product Description

Product Description:


Silicon carbide is a compound with the chemical formula SiC. It is produced by melting together quartz sand, petroleum coke or coal coke, wood chips (with the addition of salt for the production of green silicon carbide) and other raw materials in a furnace at high temperatures. It is also known as electrolon sand or refractory sand. Silicon carbide can be classified into two types: black silicon carbide and green silicon carbide. They both have a hexagonal crystal structure with a specific gravity of 3.20~3.25g/cm3 and a Mohs hardness of 9.5. The production of silicon carbide involves various chemical processes. Black silicon carbide contains about 98.5% SiC and has higher toughness compared to green silicon carbide.



Black silicon carbide is a tough and long-lasting material used for abrasives. It boasts impressive qualities such as exceptional thermal conductivity, great strength at high temperatures, and minimal thermal expansion. Its distinct crystal structure allows it to withstand wear and deformation with ease. Additionally, black silicon carbide is highly resistant to chemical reactions, making it an ideal choice for use in harsh chemical environments.


Technical Parameters:


chemical constitution SiC ≥98.6%
Fe2O3 ≤0.37%
physical properties colour black
Mohs hardness 9.3
true density 3.20~3.25g/cm3
bulk density 1.20~1.6g/cm3





Black silicon carbide is a commonly used abrasive material in various forms, including grinding wheels, belts, and discs. It is primarily used for surface preparation, removing excess material, and achieving a smooth finish.



For precision cutting and shaping of hard and brittle materials, black silicon carbide is the ideal choice for cutting tools like saw blades and drill bits. Its high strength and hardness make it effective for a variety of cutting tasks.
