A Si3N4 is a covalent bonding compound. The basic structural element is the [SiN4] Tetrahedron. The silicon is in the middle of the tetrahedron. Four nitrogen atoms surround it. They are located on the four vertices. The tetrahedrons have the same form as an atom. They are connected in a three-dimensional network.
Si3N4 ceramics used as structural materials: examples
It can be used for ball bearings because of its high rigidity, lightweight, and low weight. It generates less energy, is more precision than metal, and can be used in high temperatures and with corrosive media. It has heat resistance and wear resistance. The ceramic Si3N4 steam nozzle showed no damage even after a few month’s use in a 650-degree boiler. Si3N4 can be used for ball bearings because of its high rigidity and lightweight.

It shows no damage even after a few month’s use in a boiler with 650 degrees.
Si3N4 ceramics are widely used in a wide range of applications
Si3N4 will become more popular as its production, processing, molding and sintering technology improves. The ceramics of Si3N4 have many properties, including high wear resistance. They also have corrosion resistance. It is resistant to harsh environments, where metals and polymers are hard to work with.
Si3N4 ceramics are classified as high-temperature structure ceramics due to their superior mechanical properties, thermal characteristics, and chemical stability compared to other high-temperature structures ceramics. The material that has the most potential for application.
