Silicon carbide is widely used in industrial applications due to its exceptional hardness, thermal conductivity, and resistance to wear and corrosion. It serves as a key material in the production of abrasives, including grinding wheels, sandpapers, and cutting tools, where its hardness enables efficient machining of metals and ceramics.

In the electronics industry, silicon carbide is used as a semiconductor material in high-temperature, high-voltage, and high-frequency devices. Its wide bandgap allows for more efficient power conversion in devices like electric vehicle inverters, power supplies, and solar inverters, leading to reduced energy loss and improved performance.

It is also employed in refractory linings and kiln components because it can withstand extreme temperatures without deforming or degrading. Additionally, silicon carbide is used in automotive brake systems and ceramic armor due to its lightweight and high strength.

In the metallurgical sector, it acts as a deoxidizer and a carbon and silicon additive in cast iron and steel production. Its ability to enhance thermal shock resistance makes it suitable for components in furnaces and gas turbines.

More recently, silicon carbide has gained importance in LED technology, where it functions as a substrate for growing gallium nitride layers in blue and white LEDs, contributing to energy-efficient lighting solutions.
