Silicon Nitride Ceramic Connection Partsmerits
Silicon nitride ceramic components exhibit a low thermal expansion coefficient and high thermal conductivity, resulting in exceptional thermal shock resistance. At temperatures below 1200°C, silicon nitride ceramics demonstrate high strength and impact resistance.
Description
Advantages of Silicon Nitride Ceramic Connecting Components
Silicon nitride ceramic connectors exhibit exceptional hardness and self-lubricating properties, making them highly wear-resistant. Furthermore, silicon nitride ceramics resist corrosion by remaining inert to all inorganic acids except hydrofluoric acid. Additionally, they demonstrate outstanding thermal shock resistance, remaining intact even when heated to 1000°C in air and then rapidly cooled.
Applications of Silicon Nitride Ceramics
Silicon nitride ceramics have excellent mechanical, thermal and electrical properties. It is also one of the most thermodynamically stable high hardness industrial ceramic materials. It is ideal for bearing parts, especially those that need to work at high temperatures and pressures. Therefore, silicon nitride ceramic products are ideal for many industries, such as:
- Rotary ball and roller bearings
- Cutting Tools
- Engine components: valves, rocker gaskets, sealing surfaces
- Induction heating coil holder
- Turbine blades, wheel blades, buckets
- Welding and brazing fixtures
- Heating Element Assemblies
- crucible
Basic Properties of Silicon Nitride Ceramics
Silicon nitride ceramics are an inorganic ceramic material. Silicon nitride is very strong, especially hot pressed silicon nitride, which is one of the hardest materials in the world. It is characterized by high strength, low density and high temperature resistance.
