Advantages Of Silicon Nitride Ceramic Stopper

The silicon nitride ceramic stopper has super hardness, it has lubricity and is very resistant to wear. Except for hydrofluoric acid, it does not react with other inorganic acids and has strong corrosion resistance. Moreover, it can resist the impact of cold and heat. It will not be broken when heated to 1,000°C or higher in the air, and then rapidly cooled and heated again.

Silicon Nitride Ceramic Stopper Applications

Silicon nitride ceramic has excellent mechanical, thermal and electrical properties. It is also one of the most thermodynamically stable high-hardness industrial ceramic materials. It is an ideal choice for bearing parts, especially those parts that need to work under high temperature and high pressure. Therefore, silicon nitride ceramic products are an ideal choice for many industries, such as:

• Rotating ball & rollers bearings
• Cutting tools
• Engine components: valves, rocker arm pads, seal faces
• Induction heating coil supports
• Turbine blades, vanes, buckets
• Welding & brazing jigs
• Heating Element components
• Crucibles
