Silicon Nitride
Silicon Nitride (Si3N4) is a kind of Technical Ceramics that does not shrink during sintering. This advanced ceramic has the characteristics of high strength, low density, and high-temperature resistance. In particular, hot-pressed silicon nitride is one of the hardest materials in the world. In addition, Si3N4 has a low thermal expansion coefficient and high thermal conductivity, so it has excellent thermal shock resistance.
Si3N4 ceramic occupies an increasingly important position in the industry as an engineering structural ceramic. Compared with other high-temperature structural ceramics such as oxide ceramics and carbide ceramics, Si3N4 Ceramics have better mechanical properties, thermal properties and chemical stability, and can be used as high-temperature structural parts such as automobile engines, gas turbines, and combustion chambers.
We currently produce a variety of silicon nitride customized Ceramic parts such as silicon nitride ceramic nozzles, silicon nitride Ceramic Rods, silicon nitride thermocouple protection tubes in various welding appliances, silicon nitride ceramic heating components in automation and gas equipment, and electrically insulating Ceramic Components.

Product Advantages
Higher Hardness and Self-lubricating
The hardness is second only to a few super hard materials such as diamond, cubic BN, and B4C, and it has a small friction coefficient and is wear-resistant.
Thermal shock resistance is the best among ceramics
Silicon nitride has excellent thermal shock resistance and good thermal fatigue performance. It will not break when heated to above 1000℃ in the air, cooled rapidly and then heated rapidly.
Chemically Stable and Corrosion-resistant
Except for hydrofluoric acid and hot phosphoric acid, it does not react with other inorganic acids and has strong corrosion resistance.
Good Electrical Insulation Properties
Silicon nitride has high breakdown electric field strength and low dielectric constant. Therefore, it is often used as high-voltage insulating material and insulating layer of electronic devices.
