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 semiconductor industry, silicon carbide is used as a substrate for electronic devices, especially high-temperature, high-voltage, and high-frequency applications such as power electronics and LED manufacturing. Its wide bandgap allows devices to operate more efficiently than traditional silicon-based components.

It is also employed in refractory linings for furnaces and kilns, where it provides excellent thermal shock resistance and structural stability at high temperatures. Additionally, silicon carbide is used in automotive brake systems and ceramic armor due to its lightweight and high strength.

In the energy sector, it plays a role in solar inverters and electric vehicle power systems, contributing to improved energy efficiency and reduced heat loss. Its use in composite materials and coatings further extends its application in aerospace and defense technologies.
