Silicon Nitride Ceramic Feature And Application

There are many types of special ceramics and structural ceramics, silicon nitride ceramic is known as the “King of Structural Ceramics” due to its balanced performance in all aspects. It is suitable for applications with large mechanical vibration, large thermal shock, high current impact, and require high reliability and stability. The purity, particle size, and crystal form of silicon nitride ceramic powder have a significant impact on the substrate molding process, sintering process, and final product performance. Therefore, the preparation process of silicon nitride powder is particularly important.

Silicon Nitride Ceramic Bearings
Silicon nitride ceramic components have excellent mechanical properties, thermal properties, electrical properties and chemical properties, and is widely used in various fields. Such as Si3N4 ceramics is an excellent material for preparing ceramic substrates in various applications. Here are some common application for reference:

 

1. Refractory material: Silicon nitride has the characteristics of high melting point, high hardness, low expansion coefficient, etc., and is an excellent refractory material. It can be used to make refractory bricks, refractory castables, refractory coatings, etc., and is used in high-temperature kilns and equipment in steel, nonferrous metals, glass and other industries.

 

2. Electronic materials: Silicon nitride can be used to manufacture packaging materials, heat sinks, insulating materials, etc. for semiconductor chips, as well as microwave communication devices, optoelectronic devices, etc.

 

3. Abrasive part: Silicon nitride can be used to make abrasives part, such as grinding wheels, grinding heads, grinding discs, etc., for grinding hard materials such as steel, non-ferrous metals, glass, etc.

 

4. Bicycle industry: Excellent high-temperature mechanical properties, wear resistance and corrosion resistance feature let SI3N4 parts can be used to manufacture ceramic engine parts, ceramic cutting tools, ceramic bearings, ceramic molds, etc. High-end bicycle accessories products use silicon nitride bearings and rear derailleur guide systems using mold injection carbon fiber technology.

 

5. Aerospace materials: Silicon nitride has excellent mechanical properties and corrosion resistance. It can be used to manufacture engine parts, wings, fuselages, etc. of aerospace vehicles, as well as solar panels, antennas, etc. for satellites.

 

6. Automobile industry: Silicon nitride can be used to manufacture automobile engine parts, brake pads, clutch plates, etc., as well as automobile tires, wheel hubs, etc.

 

In short, silicon nitride is an inorganic non-metallic material with widely application. With the continuous development of science and technology, its application fields will continue to expand.
