Silicon Nitride Ceramic Disc Gasketmerits
Silicon nitride's extremely high flexural strength and dimensional stability, in the thin disc structure, can also maintain excellent flatness for a long time, not easy to warp and deform, high material hardness, low coefficient of friction, disc in the contact friction and high-frequency compression environment has a very long life. With its simple and high-precision structure and excellent material properties, silicon nitride ceramic disc structure has high value in high temperature, wear-resistant, insulating and high-clean environment.
Description
Advantages of Silicon Nitride Ceramic Discs
Silicon nitride ceramic disc structural parts are designed with standard round piece type solid structure, simple shape, and very high requirements for dimensional accuracy and surface quality.
- Standard disc body construction provides uniform force and stable support for rotary applications.
- Double-sided high-precision grinding planes with excellent flatness and thickness consistency to meet the requirements of high-precision equipment assembly.
- Highly concentric outer edges ensure mounting positioning and rotational stability.
- Micro-beveled edges reduce the risk of chipping and improve handling and assembly safety.
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.
