Silicon Nitride Powder


Silicon nitride is a kind of non-oxide ceramic, with high degree of thermal stability and excellent chemical stability, it has been developed specifically for advanced ceramic applications like bearing parts, cutting tools, valve parts and corrosion-resistant structural components.


  • High resistance to temperature fluctuations
  • Highhardness and fracture toughness
  • High resistance to wear and corrosion
  • High Purity and α–phase crystal content
  • Light weight makes it an alternative solution for steel components
  • High ductility
