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. However, different industries require various specifications. Below are some typical applications of the black SiC powder:
| Specification | Diameter size | Applications |
| F1200 | 3-4 microns | Sintered SiC ceramic, DPF ceramic filter |
| F1000 | 4-6 microns | Wear resistance coating for pipe protection, Anti-slip powder for vehicle brake. |
| F800 | 6-8 microns | Copper instrument polishing, Deburring & tumble grinding metal, and alloy, Modified epoxy resin filler |
| F600 | 8-10 microns | Glass artwork polishing, Jade polishing |
| F500 | 11-14 microns | Crystal polishing, Advanced silicon carbide ceramic pumps, Heat resistant & corrosion resistant filler for FRP pipes. |
| 1000# | 16-19 microns | Resin bonded diamond cutting abrasive disc. |
| F400 | 21-24 microns | Glass artwork polishing, Polishing Ceramic capacitor, Frankfurt grinding block, Resin bonded diamond cutting abrasive disc |
| F360 | 22-25 microns | Crystal polishing, Refractory castable, Thermal insulted coating, DPF ceramic filter |
| F320 | 38-42 microns | Oil lubricant filler, Desulfurization tower repair coating, Modified epoxy resin filler, Advanced silicon carbide ceramic pumps, heat resistance & wear resistance paint filler |
| F280 | 32-36 microns | Lapping ceramic components in the power industry, etc. |
| F240 | 44-48 microns | Oil lubricant filler, Sintered SiC ceramic, heat resistance & wear resistance paint filler. |
| P240-P5000 | Coated abrasives such as water sanding paper, nylon sand wheel,etc. |
