What is the Definition of Black Silicon Carbide?

Black Silicon Carbide (SiC) is produced from recycled feed including amorphous SiC from previous furnacing cycles; the black coloration comes from iron impurities. Black Silicon Carbide is of a lower purity (95–98%) and consists of the alpha phase with both hexagonal and rhombohedra forms.

Black silicon carbide powders are the perfect material that specifically manufactured to be used for general abrasive applications in bonded abrasive tools, lapping and polishing processes. While silicon carbide has lower hardness and abrasive capacity than diamond and boron carbide, it is widely used for grinding non-ferrous materials, finishing tough and hard materials, filling up ceramic parts when the processing cost is important.

Application:
1. The most widely application of silicon carbide is producing abrasive tools, such as grinding wheels, cutting disks, etc. Black silicon carbide powder also could be used as lapping and polishing media.
2. Black SiC is suitable for processing glass, ceramics, stone, metal, rubber and other materials.
3. Black Sic also can be used as metallurgical additive and high-grade Silicon Carbide Refractory Material.
