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

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.
