Silicon nitride ceramic processing parts

Silicon nitride ceramic processing parts

Silicon nitride ceramics can be used in the preparation of porous ceramics. Porous silicon nitride ceramics have both the properties of silicon nitride ceramics and porous materials. They have both high strength, good toughness, good creep resistance and good structural stability of silicon nitride ceramics. , anti-rain erosion, excellent thermal shock resistance, etc., and also has the characteristics of small porous material density, low dielectric constant and dielectric loss. Therefore, porous silicon nitride can be used in aviation and aerospace fields, as a The radome made of silicon nitride ceramics can be used in 7Ma high-speed aircraft, and has high strength, good thermal shock resistance and rain erosion resistance.

Compared with other high-tech ceramic materials, silicon nitride has obvious advantages in mechanical, thermal and electrical performance. It is a high-performance technical ceramic with high hardness and excellent thermal shock resistance. It exceeds the high temperature capabilities of most metals and has excellent creep and oxidation resistance. Additionally, its low thermal conductivity and high wear resistance make it an excellent material that can withstand the toughest conditions in demanding industrial applications and still function. Especially when high temperature and high load requirements are required, silicon nitride is an excellent choice.

Silicon nitride ceramic characteristics:

1. High strength in a large temperature range

2. High fracture toughness

3. Good elastic strength

4. Mechanical fatigue and creep resistance
