Product Description

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:

  It is broadly used as refractory material and metallurgical deoxidant.
