Silicon nitride The ceramics material is synthetic. The covalent bonds between silicon atoms, and nitrogen atoms are strong in the ceramic’s structure. The silicon nitride is characterized by high strength, hardness, corrosion resistance and oxidation resistance.
Material industry has a high regard for silicon nitride materials as engineering ceramics with good properties. They can be used at high temperatures.

Properties and applications of silicon-nitride ceramics

Normal temperature strength and high fracture toughness are characteristics of silicon nitride. They will maintain their strength at high temperatures. These are its main performances:

1. Material made of silicon nitride has a low coefficient of linear expansion, excellent thermal conductivity and thermal shock resistance.

2. The hardness is very high, at 99.5. Only a few materials are harder, such as diamonds and BN.

It is also self-lubricating, wear-resistant and has a low friction coefficient.

4. Silicon nitride is a good material with good mechanical properties.

5.Silicon Nitride material is good at high temperature and has good insulation properties;

Silicon Nitride Ceramics: Applications

Si3N4 ceramics have been used widely in many industries due to its excellent properties.

In the machine industry, silicon-nitride ceramics can be found in turbine blades as well as mechanical seal rings, bearings for high temperatures, high speed cutting tools and permanent molds. ;

The metallurgical industries use silicon nitride ceramics as part of thermal equipment like crucibles, aluminum reduction cell linings, and burners.

Chemical industry uses silicon nitride as a corrosion and wear resistant ceramic for parts such as pump bodies, ball valves or burners. ;

Silicon nitride Ceramics are used in electronics as high temperature insulators, film capacitors, and as high-temperature insulators;

As radomes and engines, silicon nitride is used. Aerospace industry

Ceramics made of silicon nitride are used by the atomic industry to support and space nuclear reactors. They can also be used as carriers for fissionable materials.
