Silicon carbide is not only a commonly used abrasive, but also has many other applications due to its stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and good wear resistance. One such application involves coating turbine impellers or cylinder blocks with silicon carbide powder, which enhances their wear resistance and longevity by up to 2 times. This mineral is also a high-grade refractory material with heat shock resistance, light weight, small volume, high strength, and excellent energy-saving properties. Low-grade silicon carbide, which contains about 85% SiC, is an excellent deoxidizer that expedites steelmaking, allows for easier regulation of chemical composition, and improves steel quality. Additionally, silicon carbide is widely used to create electric heating elements such as silicon carbide rods.
Silicon carbide is known for its exceptional hardness and remarkable thermal conductivity properties. This unique compound is also a proficient semiconductor that can endure oxidation even when subjected to high temperatures.
