Silicon Nitride Plate is a commonly used ceramic material in the metallurgical industry due to the even performance in high temperatures. Silicon Nitride Plate has excellent thermal shock resistance due to the microstructure. The creep and oxidation resistance of Silicon Nitride is also superior, its low thermal conductivity and high wear resistance also make it an outstanding material that can withstand conditions of most industrial applications.
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. Silicon nitride ceramic products are therefore ideal for many industries, such as:
Rotary ball and roller bearings
Cutting tools
Engine components: valves, rocker gaskets, seal rings
Induction heating coil supports
Turbine blades, wheel blades, buckets
Welding and brazing fixtures
Heating element assemblies
