Green Silicon Carbide
Products Description
Green Silicon Carbide (Green SiC) is a premium synthetic abrasive material manufactured in an electric resistance furnace using high-purity silica and petroleum coke under extremely high temperatures.
Known for its exceptional hardness, sharp cutting edges, and high chemical purity, Green Silicon Carbide is widely used in precision grinding, fine polishing, technical ceramics, and semiconductor-related applications, where surface quality and dimensional accuracy are critical.
Compared with black silicon carbide, green silicon carbide delivers higher cutting efficiency and better surface finish, making it the preferred choice for demanding applications.
Key Advantages
Extremely High Hardness
Green Silicon Carbide is one of the hardest abrasive materials available, second only to diamond and boron carbide. Its hardness ensures efficient grinding of hard and brittle materials.
01
Sharp and Consistent Grain Structure
The crystal structure of green SiC produces sharp, well-defined cutting edges, enabling fast material removal with minimal surface damage.
02
High Purity & Stable Performance
