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.
