98% Purity Silicon Carbide Abrasives

Black silicon carbide is used in a variety of ways in the foundry industry. Here are some of the most common applications:

Refractory Material: Black silicon carbide is a highly refractory material, meaning it can withstand high temperatures and thermal shock. As a result, it is often used as a lining material for furnace hearths and as a crucible material for the melting and casting of metals. Its high thermal conductivity, low thermal expansion coefficient, and excellent resistance to thermal shock make it an ideal material for these applications.

Abrasive: Black silicon carbide is also used as an abrasive in foundry applications. It is used for grinding and polishing cast iron, steel, and non-ferrous metals, as well as for cutting and shaping refractory materials such as fire bricks. Its hardness and toughness make it an effective abrasive material that can remove material quickly and efficiently.

Additive: Black silicon carbide can also be added to casting sands to improve their performance. It can improve the flowability of the sand, reduce gas defects in the casting, and improve the surface finish of the final product. It can also be added to coatings and binders to improve their adhesion to the mold and prevent defects such as veining and scabbing.
