36 mesh black silicon carbide for sand wheel making

Product: Silicon carbide

Raw material: Quartz sand, coal tar

Color: Black/ Green

Usage: Sand wheel making

Common size: 36 mesh

Packing: 25kg/bag


Silicon carbide (carborundum) is made of high-quality silica as its main raw materials, add quartz sand and coke / (Green one add Nacl ) as additive, smelted by high temperature furnace. Its hardness is between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp.

Characteristic 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.

Application of silicon carbide

  • Sand wheel making
