Description
Black Silicon Carbide Powder #800 is a high-purity silicon carbide micropowder produced from premium petroleum coke and silica sand through high-temperature electric resistance furnace smelting, followed by precision milling and particle classification.
With exceptional hardness, sharp particle morphology, and highly uniform particle size distribution, Black Silicon Carbide Powder #800 delivers excellent cutting efficiency while producing smooth and consistent surface finishes. Its fine particle size makes it ideal for applications requiring high-precision material removal and superior surface quality.
Compared with Black Silicon Carbide Powder #400, #800 provides a finer particle distribution that enhances polishing performance, reduces surface roughness, and improves processing accuracy while maintaining excellent abrasive efficiency. It is widely used in precision grinding, lapping, polishing, optical glass processing, ceramic manufacturing, stone finishing, refractory materials, and other advanced industrial applications.
With excellent wear resistance, thermal stability, and reliable quality, Black Silicon Carbide Powder #800 is an ideal abrasive material for manufacturers requiring consistent micropowder performance in precision finishing and industrial processing.
