Silicon Nitride (Si3N4)

Silicon Nitride (Si3N4) – Non-oxide Ceramics
Silicon nitride (Si3N4) has better high temperature capabilities than most metals combining retention of high strength and creep resistance with oxidation resistance. They are nearly as light as silicon carbide (SiC), but their microstructure gives them excellent thermal shock resistance and their high fracture toughness makes them resistant to impacts and shocks.
