Silicon carbide powder and silicon carbide particles are excellent raw materials for refractory products. It can increase the compressive strength, thermal erosion resistance, thermal stability, and oxidation resistance of refractory materials. Silicon carbide can greatly improve the thermodynamic properties of refractory products. It is mainly used for sintered silicon carbide ceramic refractory products, refractory clay, refractory bricks, refractory lining materials, refractory castables, refractory silicon carbide foam ceramics, and other products. Silicon carbide has a significant impact on the porosity and bulk density of these products,

Green silicon carbide F150 F180 grits are usually for brake abrasion. Green carborundum is a non-metallic material. However, by adding SiC to the powder metallurgy, the sintered brake will get better performance. It has the characteristics of good thermal conductivity, wear resistance, and strong heat resistance. The excellent brake pads with SiC are mainly due to the characteristics of green silicon carbide abrasive sand:

Silicon carbide (SiC), also known as carborundum sand, is rarely found in nature and is commonly used as a synthetic raw material in industry. It gains excellent properties of thermal resistance and wear resistance. It has two crystal forms: low-temperature morphology β- SiC, belonging to cubic structure, and high-temperature form α- SiC belonging to the hexagonal structure.  Silicon carbide has two types according to color: green silicon carbide and black silicon carbide.

90% purity silicon carbide is a kind of second-grade black silicon carbide. The silicon carbide purity is not less than 90%, ranging from 90% to 92%. 90% purity black silicon carbide mostly works as a refractory and metallurgy material instead of abrasive.

Silicon carbide castable, also known as SiC castable. It is a type of non-shape refractory material made from carborundum powder and other materials. It serves several functions in various applications:
