The Introduction of Silicon Carbide

As the leading manufacturer of silicon carbide and other abrasives products, we are committed to providing high- quality products to customers. Today, we’re gonna discuss the topic of what is silicon carbide used for and the specific applications of silicon carbide in many industries.

What is Silicon Carbide?

The combination of silicon and carbon is called silicon carbide, or carborundum. Although it naturally exists as the incredibly rare mineral moissanite, it has been mass-produced as a powder and crystal for abrasive purposes since 1893.

Advantages of Silicon Carbide

Compared with other materials, such as SiN and SiO2, silicon carbide has higher thermal conductivity and chemical stability.

It can maintain excellent mechanical performance in a high-temperature environment.

At the same time, it has a lower coefficient of thermal expansion, making it have better performance in high-temperature applications.

Applications of Silicon Carbide

Due to the unique properties of silicon carbide, it has a wide range of applications in many fields. Among them, there are four basic applications of silicon carbide.


The high hardness property of silicon carbide makes it suitable for applications requiring abrasives.

Specific Examples of Abrasive Properties

Abrasive instruments like grinding wheels, sandpaper, abrasive belts, whetstones, grinding blocks, grinding heads, and abrasive pastes can be made from silicon carbide.


With excellent wear resistance, silicon carbide is the second hardest material after diamond. It is the perfect material for cyclones, pump chambers, impellers, hopper linings, and wear-resistant pipes.

Specific Examples of Metallurgical Properties

It can be used as a deoxidizer and special materials in metallurgical operations, alumina smelting, etc.

*Functional Ceramic

In high-temperature and high-frequency ranges, silicon carbide is extensively utilized in high-temperature bearings, plates, nozzles, high-temperature corrosion-resistant components, and electronic equipment components.

Specific Examples of Functional Ceramic Properties

Valve Seat; Sliding Bearing; Machinery Seal

Plunger Seal Ring (Water Ring Pump); Consumable Parts (Wire Guide)

Cellar Equipment Crucible;Heat Exchanger


SiC is widely used as a high-performance refractory material or as an additive to improve the performance of refractory materials

Specific Examples of Refractory Properties

Steelmaking; Ceramic/High-Temperature Insulators

Glass manufacturing; Industrial coatings; Heat Exchanger; Kiln
