  1. Black SIC Description:
  
  
  
  ♦ The black silicon carbide is of high hardness, brittleness.
  
  ♦ Chemical washed and water washed good cleanness.
  
  ♦ It has sharp knife-edge and friable character as well as good thermal conductivity and quick heat dissipation.
  
  ♦ Black silicon carbide is produced in an electric resistance furnace from quartz sand ,petroleum coke and anthracite at high temperature.
  
  
  
  2. Applications
  
  
  
  ♦ Low tensile strength material. eg. glass, china.
  
  ♦ Ceramics, resin, rubber grinding wheel, refractory material.
  
  ♦ Sandblasting, dry grinding, free grinding as well as cutting and making jewelry, jade, agate.
  
  ♦ Grinding of gray cast iron, white cast iron, bronze, brass, ore, bone, glass, leather, rubber, plastic and the thermal sensitive material.

  4.Company Brief:
  
  
  
  Zhengzhou Yellow River (ZYR) Abrasives Co. Ltd , which was founded in 1976, is a main manufacturer in China
  
  
  
  We supply Black/Green Silicon Carbide, White/Brown Fused Aluminum Oxide.
  
  
  
  The production and quality are in accord with GB, ISO, JIS, Standard or conform to specific request.
  
  
  
  
  
  5. Advantages:
  
  
  
  (1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.
  
  
  
  (2) Good hardness, longer life.
  
  
  
  (3) Chemical washed and water washed good cleanness.
  
  
  
  (4) Special treated products get higher purity, better toughness, and better grinding effect.
