Silicon Nitride Material By Ortech Advanced Ceramics

Not only does Ortech Inc. provide a wide selection of technical and advanced ceramics including Alumina Oxide, Zirconia Oxide, Silicon Carbide we also offer the material in Silicon Nitride, which improves and extends the performance of your product, process, or system.

Silicon Nitride has good high temperature strength, oxidation resistance and creep resistance. In addition, its low thermal expansion coefficient gives good thermal shock resistance compared with most ceramic materials.

Parts are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties. The material is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts with a striking appearance.

Typical Silicon Nitride applications include:

  • Bearing balls and rollers

  • Cutting tools

  • Valves, turbocharger rotors for engines

  • Turbine blades

  • Glow plugs

  • Molten metal handling

  • Thermocouple sheaths

  • Welding jigs and fixtures

  • Welding nozzles

    Silicon nitride is a rather expensive material, but it's performance to cost benefit ratio is excellent in the applications where it can outperform the normally utilized materials with long life and very reliable low maintenance operation.
