Description

Advantages of Silicon Nitride Ceramic Discs
Silicon nitride ceramic disc has excellent comprehensive performance, manifested as high strength, good toughness, not easy to rupture in the force or impact conditions; also has excellent high temperature resistance, in a high temperature environment can still maintain stable performance, not easy to deformation or failure. In addition, its high hardness, wear resistance, suitable for long-term use in friction conditions. The material also has good thermal shock resistance, can withstand rapid temperature changes without cracking, and excellent corrosion resistance.
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
