Replacing the conventional approach of using silicon powder and carbon powder for deoxidation, the employment of silicon carbide as a powerful composite deoxidizer has emerged as a groundbreaking innovation in this domain. With better efficacy and stronger performance, silicon carbide is increasingly being referred to as the go-to solution for deoxidization processes.
Silicon carbide, a popular abrasive material, comes in two variations: black silicon carbide and green silicon carbide. The manufacturing process for each type differs slightly.
Black silicon carbide is produced by smelting quartz sand, petroleum coke, and high-quality silica in a resistance furnace at high temperatures. This combination of raw materials results in the formation of black silicon carbide.
On the other hand, green silicon carbide is made by smelting petroleum coke and high-quality silica in a resistance furnace. To enhance its properties, a small amount of salt is added as an additive during the smelting process. The outcome is green silicon carbide.
In summary, both black and green silicon carbide originate from the same base materials but undergo distinct manufacturing treatments. These processes yield the two variants used in various industrial applications.

Black and green Silicon Carbide /SiC
High-quality silica and petroleum coke are the two main raw materials used in the production of green silicon carbide. This compound undergoes a smelting process in a resistance furnace, with the addition of salt as an additive. As a result of this process, green silicon carbide has a hardness rating that falls between that of a diamond and corundum. Its mechanical strength is also superior to that of corundum.
