Products Description
Silicon Carbide (SiC) is a high-performance ceramic material made from silicon and carbon. It is known for its extreme hardness, high thermal conductivity, excellent chemical resistance, and thermal shock resistance. With a Mohs hardness of 9.2–9.5, it is one of the hardest industrial materials after diamond and boron carbide.
Silicon carbide (SiC), also known as corundum, is a hard compound containing silicon and carbon. It is a new type of strong composite deoxidizer, which replaces the traditional silicon carbon powder for deoxidation. Compared with the original process, its physical and chemical properties are more stable. , good deoxidation effect. Silicon carbide is usually produced in resistance furnaces at high temperatures of 1700 – 2500 °C. Silicon carbide has been an important material in sandpaper, grinding wheels and cutting tools since the late 19th century. In recent years, it has found applications in refractory linings and heating elements for industrial furnaces, wear-resistant parts for pumps and rocket engines, and semiconductor substrates for light-emitting diodes.
