220V Silicon Nitride Ceramic Air Heater

Product Description

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.
