The Applications of Silicon Nitride Ceramics

November 20, 2024

Silicon Nitride (SI3N4) is a Technical ceramic 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 is increasingly important in the industry as an engineering structural ceramic. Compared with other high-temperature structural ceramics such as oxide and carbide ceramics, SI3N4 ceramics have better mechanical properties, thermal properties, and chemical stability. They can be used as high-temperature structural parts such as automobile engines, gas turbines, and combustion chambers.

New Energy Vehicles
