Nitride Ceramics—Si3N4
The Si3N4 based ceramics have excellent properties of low
density, high strength, hardness and toughness, wear-corrosionoxidation,
thermal shock resistance low thermal expansion,
self-lubricating, heat insulation, electricity insulation
etc.
Applications:
Bearing
balls, cutting tools, heat exchanger, rotor, burner
nozzle, reaction tube, belt cleaner, extrusion dies
welding pins guide rollers, various jig, chemical plant
parts, nozzles.
