This product takes tungsten wire as heat source which is buried in silicon nitride (Si₃N₄) substrate, through hot-pressing forming, sintering, grinding, and welding wire, to obtain ignition component. Due to adopting silicon nitride ceramic (Si₃N₄) as heating substrate material, this ignition overcomes all the drawbacks that the metal sleeve electric plug possesses: no high temperature tolerance, short life and long warming up time, etc., and can be made into proper shapes to fit application requirements.

Silicon nitride ceramic (Si₃N₄) ignition features in:

• High electric insulation strength: No breakdown for 1 minute, at 2500V, 50Hz, and room temperature
• High application temperature: maximum 1200 ⁰C in air
• High power at unit surface, up to 25 W/cm²
• Small thermal inertia and fast heating, surface temperature can be increased to 1100 ⁰C in 15 seconds
• Acid and alkali corrosion resistance
• Small size and light weight
• Long service life up to 5000 h
• Power on / off circle can reach 10 million times
• Fast Preheat: when preheat temperature is 850 ⁰C, the preheating time only need 3 to 5 seconds
• Low-temperature starting performance: -30 ⁰C reliable starting
• High strength at high temperature, suitable for high-speed diesel engines and various high-temperature ignition

Silicon nitride (Si₃N₄) ignitor is widely used in domestic, industrial and commercial applications. Typical applications include:

• Oil type medium ignition
• Gas ignition
• Burner ignition
• Preheat ignition
• A variety of high-temperature ignition
