Introduction to Silicon Carbide
Silicon carbide (SiC), also known as carborundum, is a semiconductor compound composed of silicon and carbon. It has a unique combination of physical and chemical properties that make it highly valuable in a wide range of applications. Silicon carbide has a high hardness, second only to diamond, which gives it excellent wear - resistance. It also has high thermal conductivity, good chemical stability, and a wide band - gap, which makes it suitable for high - power, high - frequency, and high - temperature electronic devices.
In recent years, with the development of the new energy vehicle industry, 5G communication, and smart grid, the demand for silicon carbide has been increasing rapidly. China has become one of the important production and application regions for silicon carbide, and many domestic factories are making significant contributions to the development of the silicon carbide industry.
