Silicon carbide (SiC) is a versatile material with a wide range of applications due to its unique properties.
What are the common uses of silicon carbide? (9 Key Applications)
1. Semiconductors
Silicon carbide is widely used in the semiconductor industry. It has high thermal conductivity, high breakdown electric field strength, and can operate at high temperatures. This makes it ideal for power electronics, such as high-voltage rectifiers, high-frequency devices, and high-temperature sensors.
2. Bulletproof Vests and Ceramic Plates
Silicon carbide is used as a reinforcement material in bulletproof vests and ceramic plates. Its exceptional hardness and strength provide excellent protection against high-velocity projectiles and ballistic threats.
3. Heating Elements in Industrial Furnaces
Silicon carbide is frequently used as heating elements in industrial furnaces. It has high-temperature strength, low thermal expansion, and excellent thermal conductivity. This allows it to withstand extreme temperatures while maintaining its mechanical integrity.
4. Foundry Crucibles
Silicon carbide is used in foundry crucibles for melting and casting metals. It has high thermal shock resistance, chemical inertness, and can withstand high temperatures. This makes it a stable and durable container for molten metals.
5. Car Clutches
Silicon carbide is used in car clutches. It has high thermal conductivity, high strength, and low friction properties. This allows for efficient transfer of power and provides durability and reliability in clutch systems.
6. Heat Exchangers
Silicon carbide heat exchangers are used in various industries, such as chemical processing and power generation. They have high thermal conductivity, corrosion resistance, and can operate at high temperatures. This makes them efficient in transferring heat between different fluids or gases.
7. Ceramics and Refractories
Silicon carbide is used in the production of ceramics and refractories. It has high hardness, low density, and outstanding chemical and erosion resistance. It is used in applications such as lining blocks and bricks for blast furnaces, guide rails, and protective coatings.
8. Abrasives
Silicon carbide has been used as an abrasive material for over a hundred years. It is used in grinding wheels and other abrasive products due to its hardness and ability to remove material efficiently. It is widely used in metalworking, woodworking, and stone cutting industries.
9. High-Temperature Thermoelectric Energy Conversion
Boron carbide, which is based on silicon carbide, is used as a promising semiconductor material for high-temperature thermoelectric energy conversion. It has high stability at high temperatures and interesting thermo-electrical properties.
