Silicon Nitride Ceramic

 

There are many kinds of structural ceramics. Advantages and disadvantages and good application directions have similarities and differences. Among them, “silicon nitride ceramic” is more balanced. This balance among ceramics can be attributed to the qualities of silicon nitride.

Because the nitrogen atoms are very firmly bond, silicon nitride has good high strength, high hardness, and high temperature resistance. Itcan have hardness levels reaching HRA91-93, displaying remarkable hot hardness and the ability to withstand high temperatures of 1300-1400°C.

They have small creep at high temperatures. The slow plastic deformation produced by high temperatures and fixed loads is small. Even under stress, s3n4 ceramic demonstrates minimal deformation.

In addition, si3n4 ceramics have high specific strength and high specific mode. They also have high thermal conductivity and excellent electrical properties. So, they hold special application value in extreme environments where si3n4 ceramic properties are essential.

Application of silicon nitride ceramic:

1.Silicon nitride ceramic bearing, a prime example of utilizing this material’s attributes.

2.High-temperature parts of automotive engines benefit from silicon nitride ceramic.

3.Silicon nitride ceramic heat dissipation substrate leverages its thermal properties.

Applications in other fields:

They can use for chemical corrosion-resistant and wear-resistant parts and sealing rings. The unique high-temperature resistance, paired with corrosion resistance, enhances their applications.
