Facts about Si3N4

There exist three crystallographic structures of silicon nitride (Si3N4), designated as α, β and γ phases.The α and β phases are the most common forms of Si3N4, and can be produced under normal pressure condition. The γ phase can only be synthesized under high pressures and temperatures and has a hardness of 35 GPa.

Automobile industry


One of the major applications of sintered silicon nitride is in automobile industry as a material for engine parts. Those include,

  • In diesel engines, glowplugs for faster start-up;
  • Precombustion chambers (swirl chambers) for lower emissions, faster start-up and lower noise;
  • Turbocharger for reduced engine lag and emissions. In spark-ignition engines, silicon nitride is used for rocker arm pads for lower wear, turbocharger turbines for lower inertia and less engine lag, and in exhaust gas control valves for increased acceleration. As examples of production levels, there is an estimated more than 300,000 sintered silicon nitride turbochargers made annually
