Specifications

Black silicon carbide grit F grade 20-220#; sic90% and 97%min grains sized in 0-1mm,1-3mm,3-5mm,1-10mm, sic80%-88% etc 

1. Description:
    Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand

    and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond.

    Mechanical intensity of it is higher than fused alumina. It is sharp and has electrical and heat conductivity in

    some degree.
2. Application:
   ♦As the abrasive: used for abrasive, such as grinding wheels, whetstone, grinding wheel, sand tiles etc.
   ♦As the metallurgical deoxidizer and high temperature material.
     Four main application areas of SiC: functional ceramics, advanced refractory, abrasives and metallurgical materials.
   ♦High purity single crystal, used to manufacture semiconductors, manufacture of silicon carbide fibers.
   ♦Silicon carbide is very hard, with excellent thermal conductivity, as a semiconductor and high temperature

     resistant to oxidation.
3. Partical Size:
   ♦Lumps: 0-20mm, 0-50mm.
   ♦Grains: 0-1mm, 1-3mm, 3-5mm, 5-8mm, 0-10mm, 1-10mm, etc. 7/14, 14/30, 36/70, etc. -100mesh,
