BLACK SILICON CARBIDE

Black silicon carbide is produced in electrical internal resistance furnaces from high purity silica sand and petroleum coke. Its hardness and sharp angles make it ideal for bonded, coated and loose abrasive applications.

Advantages
  • Environmentally friendlier than chemical treatments
  • Fine blasting media
  • Suitable for dry pressure blasting equipment
  • Tightly graded according to FEPA standards
