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 metallurgy and refractory industry, it is used to line furnaces and manufacture crucibles because it can withstand extremely high temperatures without deforming. It is also employed in the production of high-performance ceramics, such as components for seals, bearings, and nozzles that must endure harsh environments. Additionally, in steelmaking, it acts as a source of silicon and carbon to enhance the properties of steel alloys.

Silicon carbide is a critical material in electronics, especially in semiconductor devices that operate under high voltage, temperature, or frequency conditions. It is used to make power electronic devices, LED substrates, and high-temperature sensors due to its excellent electrical properties.

Additionally, it finds use in automotive applications, such as in ceramic brake discs for high-performance vehicles and in diesel particulate filters to reduce emissions. Its ability to conduct heat efficiently while resisting thermal shock makes it ideal for heat exchangers and components in aerospace and defense systems. It is also utilized in lightweight, high-strength armor plates for ballistic protection.
