Application fields and precautions of silicon nitride ceramic igniters

Silicon nitride ceramics have the characteristics of high strength, high-temperature resistance, thermal shock resistance, oxidation resistance, wear resistance, and corrosion resistance, and are the first candidate materials for ceramics used in thermal engine parts.





The silicon nitride ceramic igniters can heat up to 800~1000°C within ten seconds, and ignite the fuel through direct heat transfer or blast heat transfer. A temperature buffer area is set on the ignition rod to protect the terminals from damage. The wire joints are insulated and encapsulated, which can effectively prevent short circuits caused by conductive ash. With proper installation and ignition procedures, silicon nitride ceramic igniters can be used safely for years.

Application fields:

  1. Biomass boiler igniter, straw incinerator igniter
  2. Gas and oil igniters (such as natural gas)
  3. Automobile exhaust and industrial waste gas treatment
  4. Gas heating (air, working gas)
  5. Pyrotechnic generator
  6. Brazing equipment
  7. Corrosive environment heater
  8. Customization of laboratory special heating elements and heating systems


  1. It is necessary to use reasonable installation methods and ignition procedures to ensure the working life of the igniter.
  2. It is necessary to determine the appropriate gas flow rate according to the selected igniter model. If the flow rate is too small, the load on the igniter will be too large, and the surface temperature will exceed the rated value. When designing the airflow channel, it should be ensured that the airflow is fully in contact with the igniter and that the heat dissipation around the igniter is sufficient.
  3. Do not place any part of the igniter in the combustion chamber.
  4. A model with a larger hot zone or a combination of multiple igniters can provide a faster ignition speed.
  5. The package end of the igniter should have good heat dissipation, and the igniter should be turned off in time after the ignition is successful.
