Silicon carbide is widely used in industrial applications due to its exceptional hardness, thermal conductivity, and resistance to wear and corrosion. It serves as an abrasive in grinding, cutting, and polishing tools, and is a key material in the production of sandpapers, grinding wheels, and cutting discs.

In the metallurgical industry, silicon carbide is used as a deoxidizer and as an additive to increase silicon and carbon content in steel and iron. It enhances the mechanical properties and performance of metals during manufacturing.

It is also employed in high-temperature environments, such as in refractory linings for furnaces and kilns, where it provides structural stability and thermal shock resistance. As a semiconductor material, silicon carbide is critical in power electronics, including diodes, transistors, and thyristors, especially in high-voltage, high-frequency, and high-temperature applications like electric vehicles and renewable energy systems.

Additionally, silicon carbide is used in ceramic brake discs for high-performance vehicles, in bulletproof vests due to its lightweight and high-strength properties, and in LED production as a substrate material. Its ability to withstand extreme conditions makes it valuable in aerospace, defense, and energy sectors.
