Deion:

• Black silicon carbide is produced at high temperature in an electric resistant furnace with quartz sand and petroleum coke as its main raw materials. It is between corundum and diamond in hardness, and it is better than corundum in mechanical strength, as it is crisp and sharp.

   

  Application:

  1.     Making Grinding wheels

  2.     Making Sand paper

  3.     Making Sand belts

  4.     Making bonded abrasive tools

  5.     As ceramic materials
