Silicon carbide
Silicon carbide is an inorganic substance with the chemical formula SiC. It is made of raw materials such as quartz sand, petroleum coke (or coal coke), and sawdust (salt is needed to produce green silicon carbide) through high-temperature smelting in a resistance furnace. Silicon carbide is a semiconductor that exists in nature in the form of the extremely rare mineral moissanite. Since 1893, it has been mass-produced as powder and crystals for use as abrasives, etc. Among non-oxide high-tech refractory raw materials, silicon carbide is the most widely used and economical one, which can be called diamond sand or refractory sand.
Silicon carbide is an important industrial material with a wide range of applications. First, silicon carbide is an important abrasive that can be used for grinding and polishing materials such as metals, ceramics and glass. Secondly, silicon carbide is an excellent refractory material that can be used to manufacture kiln furniture, furnace linings and high-temperature insulation materials. In addition, silicon carbide is also an important electronic material that can be used to manufacture high-frequency, high-power electronic devices such as power transistors, diodes and optoelectronic devices.
Silicon carbide also has excellent chemical stability and can be used to manufacture corrosion-resistant materials such as chemical equipment and medical devices. In addition, silicon carbide can also be used to manufacture biomedical materials and coatings, such as artificial joints, teeth and bones.
In short, silicon carbide is a very important material with a wide range of applications. Due to its unique properties such as hardness, thermal stability, chemical stability and electronic properties, silicon carbide has important applications in many fields. With the continuous development of science and technology, the application field of silicon carbide will continue to expand.
