Black silicon carbide for sand paper

Product: Silicon carbide

Raw material: Quartz sand, coal tar

Color: Black

Usage: Sand paper

Common size: F 16-325 mesh

Packing: 25kg/bag


Black silicon carbide is made of high-quality silica as its main raw materials, add quartz sand and coke as additive, smelted by high temperature furnace. Its hardness is between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp. It can be widely used for abrasive media or as raw material to produce abrasive tools.

Advantages of silicon carbide

  1. Corrosion resistance, high strength, high hardness.
  2. Good wear-resisting performance,resist to shock.
  3. It is a cost-effective substitute for Ferrosilicon.
  4. It has Multi-functions.
  5. It costs less than ferrosilicon and carbon combination.
  6. It has no dust nuisance while feeding the material.
  7. It can speed up the reaction.
