Silicon Nitride Ceramics for Machine Parts

　Toshiba Materials' silicon nitride is lightweight and has excellent wear resistance and corrosion resistance　properties. From these characteristics, it is used in automotive and industrial machine parts applications. Toshiba Materials manufactures and sells Silicon Nitride Ceramics parts such as ball blanks(for bearings).
　In bearing applications, silicon nitride is contributing to weight reduction and performance improvement of various applications, and leading to replacement of steel balls. Our material is widely used as standard material in the market and also designated as certified material for aircraft engine application by various companies. It was also used in the bearing of turbo molecular pumps of the Space Shuttle, which was launched from 1995.
　In addition, it has a proven track record in check valves for supply pumps for diesel engines (common rail system) that require wear resistance and high rigidity, check balls for fuel injection ports, bearing balls for aircraft engines, etc. It is also used in bearing balls of motors for electric vehicles that require electrolytic corrosion resistance characteristic and used in a wide range of fields.
