Black Silicon Carbide Polishing Abrasives - China

1 - 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.
