Silicon Nitride Solutions has long been used in high-temperature applications. In particular, it was identified as one of the few monolithic ceramic materials capable of surviving the severe thermal shock and thermal gradients generated in hydrogen / oxygen rocket engines.
Silicon nitride is often used as an insulator and chemical barrier in manufacturing integrated circuits Some key properties of silicon nitride include: low density, superior thermal shock resistance, good oxidation resistance, mechanical fatigue resistance and high wear resistance.
Typical Applications Include: reciprocating engine components, jet propulsion components, orthopedic applications, thermocouple sheaths, arc welding nozzles, chemical insulators, electrical insulators, metal cutting tools, furnace fixtures, and bearing balls. Contact us for more info.
