BLACK SILICON CARBIDE

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: ***0mm, ***0mm.

   ♦Grains: **1mm, **3mm, **5mm, **8mm, ***0mm, ***0mm, etc.

                 7/*4, *4/*0, *6/*0, etc.

                ***0mesh, ***0mesh, ***5mesh, etc.

   ♦Grits: F****0, F******0.

   ♦Micropowder: F*******0.
