Silicon Carbide (SiC) is a high-hardness, high-temperature industrial material widely used for grinding, polishing, refractories, and metallurgical applications. It is available in a full range of grit sizes from 4# to 1200#, including 60#, 80#, 90#, 180#, 220#, 400#, 600#, 1000#, and more, to meet various precision processing and industrial requirements. With excellent hardness, thermal conductivity, and chemical stability, Silicon Carbide is ideal for abrasive tools, blasting media, kiln furniture, and high-performance refractory products.

Silicon Carbide (SiC), also known as Carborundum, is a high-performance material produced by the reaction of silica and carbon at elevated temperatures. It possesses remarkable hardness, high thermal conductivity, low thermal expansion, and excellent resistance to oxidation, corrosion, and thermal shock.
Due to its properties, Silicon Carbide is widely used as a refractory material in furnaces, kilns, and industrial heating systems. It is also a key abrasive in grinding, cutting, polishing, and sandblasting applications. SiC finds use in high-performance ceramics, mechanical seals, semiconductor components, and advanced engineering applications that require durability under extreme conditions.
